I/O PORT STRUCTURE
The P8xCE598 has six 8-bit parallel ports: Port 0 to Port 5. In addition to the standard 8-bit parallel ports, the I/O facilities
also include a number of special I/O lines. The use of a Port 1, Port 3 or Port 4 pins as an alternative function is carried
out automatically provided the associated SFR bit is set HIGH.

FUNCTION
REMARKS
Port 0
I/O
Multiplexed Low-order address and
Data bus for external memory (AD7 to AD0)
Provides the multiplexed Low-order address and
data bus used for expanding the P8xCE598 with
standard memories and peripherals.
Port 1
I/O
Capture timer inputs for Timer T2
(CT0I to CT3I), or
External interrupt request inputs
(INT2 to INT5)
External interrupt request inputs, if capture
information is not utilized.
T2 event input (T2)
External counter input.
T2 timer reset input (RT2)
External counter reset input.
CAN transmitter output 0 (CTX0)
CTX0 and CTX1 outputs of the CAN interface
(note 1).
CAN transmitter output 1 (CTX1)
Port 2
I/O
High-order address byte for external memory
(A08 to A15)
Port 2 provides the High-order address bus when
the P8xCE598 is expanded with external Program
Memory and/or external Data Memory.
Port 3
I/O
Serial Input Port (RXD)
Receiver input of serial port SIO0 (UART).
Serial Output Port (TXD)
Transmitter output of serial port SIO0 (UART).
External interrupt (INT0)
External interrupt request inputs.
External interrupt (INT1)
Timer 0 external input (T0)
Counter inputs.
Timer 1 external input (T1)
External data memory Write strobe (WR)
Control signal to write to external Data Memory.
External data memory Read strobe (RD)
Control signal to read from external Data Memory.
Port 4
I/O
Compare and Set/Reset outputs
(CMSR0 to CMSR5)
Can be congured to provide signals indicating a
match between Timer counter T2 and its compare
registers.
Compare and toggle outputs (CMT0, CMT1)
Port 5
I
Input channels to ADC (ADC7 to ADC0)
Port 5 may be used in conjunction with the ADC
interface (note 2).
