CMT0, CMT1 (P4.6, P4.7): Timer T2 compare and toggle outputs on a match with timer T2.
Digital Power Supply: +5 V 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). This pin must not float.
Pulse Width Modulation: Output 0.
Pulse Width Modulation: Output 1.
Enable Watchdog Timer: Enable for T3 watchdog timer and disable power-down mode.
This pin must not float.
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 1: 8-bit I/O port. Alternate functions include:
(P1.0-P1.5): Quasi-bidirectional 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 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 quasi-bidirectional I/O port.
Alternate function: High-order address byte for external memory (A08-A15).
Port 3: 8-bit quasi-bidirectional 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.
Port 4: 8-bit quasi-bidirectional I/O port. Alternate functions include:
CMSR0-CMSR5 (P4.0-P4.5): Timer T2 compare and set/reset outputs on a match with
timer T2.
Port 5: 8-bit input port.
ADC0-ADC7 (P5.0-P5.7): Alternate function: Eight input channels to ADC.
Reset: Input to reset the 8XC552. It also provides a reset pulse as output when timer T3
overflows.
Crystal Input 1: Input to the inverting amplifier that forms the oscillator, and input to the
internal clock generator. Receives the external clock signal when an external oscillator is
used.
Crystal Input 2: Output of the inverting amplifier that forms the oscillator. Left open-circuit
when an external clock is used.
