Digital Power Supply: Positive voltage power supply pin during normal operation, idle and
power-down mode.
Start ADC Operation: Input starting analog to digital conversion (ADC operation can also be
started by software).
Pulse Width Modulation: Output 0.
Pulse Width Modulation: Output 1.
Enable Watchdog Timer: Enable for T3 watchdog timer and disable power-down mode.
Port 0: Port 0 is an 8-bit open-drain bidirectional I/O port. Port 0 pins that have 1s written to them
float and can be used as high-impedance inputs. Port 0 is also the multiplexed low-order address
and data bus during accesses to external program and data memory. In this application it uses
strong internal pull-ups when emitting 1s. Port 0 is also used to input the code byte during
programming and to output the code byte during verification.
Port 1: 8-bit I/O port. Alternate functions include:
(P1.0-P1.5): Programmable I/O port pins.
(P1.6, P1.7): Open drain port pins.
CT0I-CT3I (P1.0-P1.3): Capture timer input signals for timer T2.
T2 (P1.4): T2 event input.
RT2 (P1.5): T2 timer reset signal. Rising edge triggered.
SCL (P1.6): Serial port clock line I
SDA (P1.7): Serial port data line I
Port 1 has four modes selected on a per bit basis by writing to the P1M1 and P1M2 registers as
follows:
Port 1 is also used to input the lower order address byte during EPROM programming and
verification. A0 is on P1.0, etc.
Port 2: 8-bit programmable I/O port.
Alternate function: High-order address byte for external memory (A08-A15). Port 2 is also used to
input the upper order address during EPROM programming and verification. A8 is on P2.0, A9 on
P2.1, through A13 on P2.5.
Port 2 has four output modes selected on a per bit basis by writing to the P2M1 and P2M2 registers
as follows:
Port 3: 8-bit programmable I/O port. Alternate functions include:
RxD(P3.0): Serial input port.
TxD (P3.1): Serial output port.
INT0 (P3.2): External interrupt.
INT1 (P3.3): External interrupt.
T0 (P3.4): Timer 0 external input.
T1 (P3.5): Timer 1 external input.
WR (P3.6): External data memory write strobe.
RD (P3.7): External data memory read strobe.
