Section 11 I/O Ports
Section 11 I/O Ports
Table 11.1 summarizes the port functions. The pins of each port also have other functions such as
input/output pins of on-chip peripheral modules or external interrupt input pins. Each I/O port
includes a data direction register (DDR) that controls input/output, a data register (DR) that stores
output data, a port register (PORT) used to read the pin states, and an input buffer control register
(ICR) that controls input buffer on/off. Port 5 does not have a DR or a DDR register.
Ports D to F and H and I have internal input pull-up MOSs and a pull-up MOS control register
(PCR) that controls the on/off state of the input pull-up MOSs.
Ports 2 and F include an open-drain control register (ODR) that controls on/off of the output
buffer PMOSs.
All of the I/O ports can drive a single TTL load with a capacitive component of up to 30 pF and
drive Darlington transistors when functioning as output ports.
Port 2 have pins for Schmitt-trigger inputs. Schmitt-trigger input is enabled for pins of other ports
when they are used as IRQ, TPU, TMR, or IIC2 inputs.
