Description
P1.5: I/O Port 1 bit 5.
MOSI: SPI master-out/slave-in. In UART SPI mode this pin is an output. During In-
System Programming, this pin is an input.
P1.6: I/O Port 1 bit 6.
MISO: SPI master-in/slave-out. In UART SPI mode this pin is an input. During In-
System Programming, this pin is an output.
P1.7: I/O Port 1 bit 7.
SCK: SPI Clock. In UART SPI mode this pin is an output. During In-System
Programming, this pin is an input.
RST: External Reset input (Reset polarity depends on POL pin. See “External Reset”
on page 33.). The RST pin can output a pulse when the internal Watchdog reset is
active.
P3.0: I/O Port 3 bit 0.
RXD: Serial Port Receiver Input.
Not internally connected
P3.1: I/O Port 3 bit 1.
TXD: Serial Port Transmitter Output.
P3.2: I/O Port 3 bit 2.
INT0: External Interrupt 0 Input or Timer 0 Gate Input.
P3.3: I/O Port 3 bit 3.
INT1: External Interrupt 1 Input or Timer 1 Gate Input
P3.4: I/O Port 3 bit 4.
T1: Timer/Counter 0 External input or output.
P3.5: I/O Port 3 bit 5.
T1: Timer/Counter 1 External input or output.
P3.6: I/O Port 3 bit 6.
WR: External memory interface Write Strobe (active-low).
P3.7: I/O Port 3 bit 7.
RD: External memory interface Read Strobe (active-low).
P4.7: I/O Port 4 bit 7.
XTAL2: Output from inverting oscillator amplifier. It may be used as a port pin if the
internal RC oscillator or external clock is selected as the clock source.
P4.6: I/O Port 4 bit 6.
XTAL1: Input to the inverting oscillator amplifier and internal clock generation circuits.
It may be used as a port pin if the internal RC oscillator is selected as the clock
source.

2.2 System Configuration
The AT89LP51/52 supports several system configuration options. Nonvolatile options are set
through user fuses that must be programmed through the flash programming interface. Volatile
options are controlled by software through individual bits of special function registers (SFRs).
The AT89LP51/52 must be properly configured before correct operation can occur.
2.2.1
Fuse Options
Table 2-1 lists the fusable options for the AT89LP51/52. These options maintain their state even
when the device is powered off, but can only be changed with an external device programmer.
For more information, see Section 17.7 “User Configuration Fuses” on page 86.
