Section 9 I/O Ports
Section 9 I/O Ports
Table 9.1 summarizes the port functions. The pins of each port also have other functions such as
input/output or interrupt input pins of on-chip peripheral modules. Each I/O port includes a data
direction register (DDR) that controls input/output, a data register (DR) that stores output data,
and a port register (PORT) used to read the pin states. The input-only ports do not have DDR and
DR registers.
Ports A to E have a built-in input pull-up MOS function and an input pull-up MOS control register
(PCR) to control the on/off state of the input pull-up MOS.
Ports 3 and A include an open-drain control register (ODR) that controls the on/off state of the
output buffer PMOS.
All the I/O ports can drive a single TTL load and a 30 pF capacitive load.
The P34 and P35 pins on port 3 are NMOS push pull outputs.
The IRQ pin is a schmitt trigger input.
