Function
Shared-function LCD driver segment output, general-purpose I/O, and serial I/O port
The IOS instruction is used to switch between the LCD driver segment output, general-
purpose I/O, and serial I/O functions, and to switch between input and output for the
general-purpose input port function.
• When used for segment output:
The function can be specified in bit units.
Segment output is specified with the IOS instruction (Pn = 0DH).
b0 = S17/PE0 0 ... Segment output
b1 = S18/PE1 1 ... PE0 to PE3 output
b2 = S19/PE2
b3 = S20/PE3
• When used as a general-purpose I/O port:
Input or output can be specified in bit units (1-bit I/O).
The general-purpose I/O port function is specified with the IOS instruction (Pn = 0).

output and
37
S19/PE2/SO2
I/O push-pull
b2 = SI/O2 0 ... General-purpose port
1 ... SI/O port
Input or output is specified with the IOS instruction in bit units.
PE ... Pn = 4 0 ... Input
36 S20/PE3/SI2
1 ... Output
• When used as a serial I/O port:
The serial I/O port function is specified with the IOS instruction (Pn = 0).
The contents of the serial I/O data buffer can be saved and loaded with the INR and
OUTR instructions.
Note: Pin setup states when used as a serial I/O port:
PE0 ... General-purpose I/O
PE1 ... SCK2 output in internal clock mode
SCK2 input in external clock mode
PE2 ... SO2 output
PE3 ... SI2 input
In clock stop mode, if this port is used as a general-purpose I/O port or as a serial I/O
port, the pins go to the input disabled high-impedance state. If used for segment output,
the pins are fixed at the low level.
The segment output port function is selected after a power-on reset.
