Port 0 can be set to the input or output mode in 1-bit units.
Port 0 has an alternate function as the following pins.
Notes 1. Software pull-up function
Cautions 1. To control the high-impedance output of a timer for motor control, be sure to set the
Port 0
2. These pins operate as Schmitt trigger inputs when they are read in the port mode.
3. The TOQH0OFF, TOQ1OFF, TOP2OFF, TOP3OFF, ADTRG0, and ADTRG1 signals are input to the

converters 0 and 1 (see CHAPTER 11 A/D CONVERTERS 0 AND 1) after noise is eliminated by a
port (analog delay). In addition, a signal whose edge was detected is input to the interrupt controller
(INTC) as INTPn (n = 0 to 5). Edge detection is performed by the high-impedance output controller and
A/D converters 0 and 1.
PMC0.PMC0n bit to 1 and then specify the edge to be detected and enable the operation of the
high-impedance output controller (n = 1 to 3), because the output of the motor control timer
may go into a high-impedance state if a wrong valid edge is detected.
then specify the edge to be detected and enable the operation of A/D converter 0 or 1 because
the trigger may be input if a wrong valid edge is detected (n = 4, 5).
PMC0.PMC0n bit from 0 to 1), an external interrupt may be input if a wrong valid edge is
detected.
INTR0.INTR0n bit = 0), select external interrupt input (INTPn), and then specify the valid edge
(n = 0 to 6).
When switching to the port mode from external interrupt input (INTPn) (PMC0n bit = 1 → 0), an
edge may be detected. Be sure to disable edge detection (INTF0n bit = 0, INTR0n bit = 0), and
then select the port mode.
