Name and Function
When this pin is low, it indicates that
address output on the address bus is
enabled.
When this pin is low, it indicates that the
external address space can be read.
A strobe signal that writes to external
space and indicates that the upper half
(D15 to D8) of the data bus is enabled.
A strobe signal that writes to external
space and indicates that the lower half
(D7 to D0) of the data bus is enabled.
It is necessary to insert a wait state into
the bus cycle when accessing the
external three-state address space.
These pins input an external clock.
TGR0A to TGR0D input capture input,
output compare output, or output PWM.
TGR1A and TGR1B input capture input,
output compare output, or output PWM.
TGR2A and TGR2B input capture input,
output compare output, or output PWM.
TGR3A to TGR3D input capture input,
output compare output, or output PWM.
TGR4A and TGR4B input capture input,
output compare output, or output PWM.
TGR5A and TGR5B input capture input,
output compare output, or output PWM.
Pulse output pins
