Table 1 Pin description for single function pins (SOT318-1 and SOT351-1; see note 1)
Notes
1. To avoid a ‘latch up’ effect at power-on: V
2. Triggered by a rising edge. ADC operation can also be started by software.
3. RST also provides a reset pulse as output when timer T3 overflows or after a CAN wake-up from Power-down.

Power supply, digital part: for internal logic (CPU, Timers/counters, Memory, CAN, UART, ADC).
Power supply, digital part: for Port 1, Port 3, Port 4, PWM0 and PWM1 outputs.
Power supply, digital part: for the on-chip oscillator.
Power supply, digital part: for Port 0, Port 2, ALE output and PSEN output.
Start ADC operation. Input starting analog-to-digital conversion (note 2). This pin must not float.
Pulse width modulation output 0.
Pulse width modulation output 1.
Enable Watchdog Timer (WDT): enable for T3 Watchdog Timer and disable Power-down mode.
This pin must not float.
Reset: input to reset the P8xCE598 (note 3).
Ground potential for the CAN transmitter outputs.
Power supply (+5V) for the CAN transmitter outputs.
Crystal pin 2: output of the inverting amplifier that forms the oscillator.
When an external clock oscillator is used this pin is left open-circuit.
Crystal pin 1: input to the inverting amplifier that forms the oscillator, and input to the internal clock
generator. Receives the external clock oscillator signal, when an external oscillator is used.
Ground, digital part: for internal logic (CPU, Timers/Counters, Memory, CAN, UART, ADC).
Ground, digital part: for Port 1, Port 3 and Port 4, and PWM0 and PWM1 outputs.
Ground, digital part: for the on-chip oscillator.
Ground, digital part: for the Port 0, Port 2, ALE output and PSEN output.
Program Store Enable: Read strobe to external Program Memory (active LOW).
Drive: 8
Address Latch Enable: latches the Low-byte of the address during accesses to external memory
(note 4). Drive: 8
External Access input. See note 5.

Inputs from the CAN-bus line to the differential input comparator of the on-chip CAN-controller
(note 7).
Low-end of ADC (analog-to-digital conversion) reference resistor.
High-end of ADC (analog-to-digital conversion) reference resistor (note 8).
Ground, analog part. For ADC, CAN receiver and reference voltage.
Power supply, analog part (+5 V). For ADC, CAN receiver and reference voltage.
No connection.
