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 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, 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 and capacitive loads up to 30 pF.
All of the I/O ports can drive Darlington transistors when functioning as output ports.
Ports 2 and 3 are Schmitt-trigger inputs. Schmitt-trigger inputs for other ports are enabled when
used as the IRQ, TPU, or TMR inputs.
