Name and Function
Data bus: These pins constitute a bidirectional data
bus.
Address strobe: When this pin is low, it indicates that
address output on the address bus is enabled.
Read: When this pin is low, it indicates that the
external address space can be read.
High write: A strobe signal that writes to external space
and indicates that the upper half (D15 to D8) of the
data bus is enabled.
Low write: A strobe signal that writes to external space
and indicates that the lower half (D7 to D0) of the data
bus is enabled.
Wait: It is necessary to insert a wait state into the bus
cycle when accessing the external three-state address
space.
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.
Input capture/ output compare match A2 and B2:
The TGR2A and TGR2B input capture input or output
compare output, or PWM output pins.
Input capture/ output compare match A3 to D3:
The TGR3A to TGR3D input capture input or output
compare output, or PWM output pins.
Input capture/output compare match A4 and B4:
The TGR4A and TGR4B input capture input or output
compare output, or PWM output pins.
Input capture/output compare match A5 and B5:
The TGR5A and TGR5B input capture input or output
compare output, or PWM output pins.
