I/O Pins and Pin Functions
Table 1.6-1 lists the MB90460/465 series I/O pins and their functions. Table 1.7-1 lists the
I/O circuit types.
The letter in the "I/O circuit type" column in Table 1.6-1 refers to the letter in the "Type"
column Table 1.7-1.

Pin status
during reset
Oscillating
Oscillation input pins.
Reset input
External reset input pin.
General-purpose I/O ports.
Output terminals OPT0 to OPT5 of the waveform
sequencer. These pins output the waveforms
specified at the output data buffer register of the
waveform sequencer circuit. Output is generated
when OPE0 to OPE5 of OPCR is enabled.
General-purpose I/O ports.
PWC 0 signal input pin.
General-purpose I/O ports.
PWC 0 signal output pin.
Port input
General-purpose I/O ports.
Can be used as interrupt request input channel 0.
Input is enabled when "1" is set in EN0 in standby
mode.
RTO0 to RTO5 pins for fixed-level input. This
function is enabled when the waveform generator
enables its input bits.
General-purpose I/O ports.
Can be used as interrupt request input channel 1.
Input is enabled when "1" is set in EN1 in standby
mode.
