General Precautions on Handling of Product
1. Treatment of NC Pins
www.DataSheet4U.com
Note: Do not connect anything to the NC pins.
The NC (not connected) pins are either not connected to any of the internal circuitry or are
used as test pins or to reduce noise. If something is connected to the NC pins, the
operation of the LSI is not guaranteed.
2. Treatment of Unused Input Pins
Note:
Fix all unused input pins to high or low level.
Generally, the input pins of CMOS products are high-impedance input pins. If unused pins
are in their open states, intermediate levels are induced by noise in the vicinity, a pass-
through current flows internally, and a malfunction may occur.
3. Processing before Initialization
Note:
When power is first supplied, the product's state is undefined.
The states of internal circuits are undefined until full power is supplied throughout the
chip and a low level is input on the reset pin. During the period where the states are
undefined, the register settings and the output state of each pin are also undefined. Design
your system so that it does not malfunction because of processing while it is in this
undefined state. For those products that have a reset function, reset the LSI immediately
after the power supply has been turned on.
4. Processing when the Power Supply Voltage is beyond the Operating Voltage Specification*
When the power supply voltage exceeds the operating voltage specification, erroneous
operation may occur. To prevent this, design your system so that it does not malfunction. For
example, the system should be reset after the power supply voltage is changed to a value
within the operating voltage specification.
Note: * The voltage must be within the range up to the absolute maximum rating. The LSI may be
permanently damaged if the absolute maximum rating is exceeded.
5. Prohibition of Access to Undefined or Reserved Addresses
Note:
Access to undefined or reserved addresses is prohibited.
The undefined or reserved addresses may be used to expand functions, or test registers
may have been be allocated to these addresses. Do not access these registers; the system's
operation is not guaranteed if they are accessed.
6. Reading from/Writing to Reserved Bit of Each Register
Treat the reserved bit of a register used in each module as follows except in cases where the
specifications for values which are read from or written to the bit are provided in the
description.
The bit is always read as 0. The write value should be 0 or one, which has been read
immediately before writing.
Writing the value, which has been read immediately before writing, has the advantage of
preventing the bit from being affected on its extended function when the function is assigned.

4페이지 • Description of Numbers and Symbols
Aspects of the notations for register names, bit names, numbers,wanwdws.DymatbaoSlhiecenta4mU.ecsoimn this
manual are explained below.
(1) Overall notation
In descriptions involving the names of bits and bit fields within this manual, the modules and
registers to which the bits belong may be clarified by giving the names in the forms
"module name"."register name"."bit name" or "register name"."bit name".
(2) Register notation
The style "register name"_"instance number" is used in cases where there is more than one
instance of the same function or similar functions.
[Example] CMCSR_0: Indicates the CMCSR register for the compare-match timer of channel 0.
(3) Number notation
Binary numbers are given as B'nnnn (B' may be omitted if the number is obviously binary),
hexadecimal numbers are given as H'nnnn or 0xnnnn, and decimal numbers are given as nnnn.
[Examples] Binary:
B'11 or 11
Hexadecimal: H'EFA0 or 0xEFA0
Decimal:
1234
(4) Notation for active-low
An overbar on the name indicates that a signal or pin is active-low.
[Example] WDTOVF
(4) (2)
14.2.2 Compare Match Control/Status Register_0, _1 (CMCSR_0, CMCSR_1)
CMCSR indicates compare match generation, enables or disables interrupts, and selects the counter
input clock. Generation of a WDTOVF signal or interrupt initializes the TCNT value to 0.
14.3 Operation
14.3.1 Interval Count Operation
When an internal clock is selected with the CKS1 and CKS0 bits in CMCSR and the STR bit in
CMSTR is set to 1, CMCNT starts incrementing using the selected clock. When the values in
CMCNT and the compare match constant register (CMCOR) match, CMCNT is cleared to H'0000
and the CMF flag in CMCSR is set to 1. When the CKS1 and CKS0 bits are set to B'01 at this time,
a f/4 clock is selected.
