Name and Function
Wait: Requests insertion of a wait
state in the bus cycle when
accessing external 3-state address
space.
CAS type DRAM lower column
address strobe signal
DMA request 1 and 0: These pins
request DMAC activation.
pins indicate the end of DMAC data
transfer.
These are the DMAC single address
transfer acknowledge pins.
Clock input D to A: These pins input
an external clock.
Input capture/ output compare match
A0 to D0: The TGR0A to TGR0D
input capture input or output compare
output, or PWM output pins.
Input capture/ output compare match
A1 and B1: The TGR1A and TGR1B
input capture input or output compare
output, or PWM output pins.
