PWC timer input pin
Since this input is used whenever the PWC0 timer is in input
operation, the output by any other function must be suspended
unless the output is intentionally performed.
PWC timer output pin
This pin is available when the PWC0 is output operation.
General-purpose I/O port
This port is available in the single-chip mode or when the upper
address control register setting is “port.”
Output pin for external address bus A21
This pin is available in an external-bus mode and when the upper
address control register setting is “address.”
PWC timer data sample input pin
Since this input is used whenever the PWC1 timer is in input
operation, the output by any other function must be suspended
unless the output is intentionally performed.
PWC timer output pin
This pin is available when the PWC1 is output operation.
General-purpose I/O port
This port is available in the single-chip mode or when the upper
address control register setting is “port.”
Output pin for external address bus A22
This pin is available in an external-bus mode and when the upper
address control register setting is “address.”
PWC timer input pin
Since this input is used whenever the PWC2 timer is in input
operation, the output by any other function must be suspended
unless the output is intentionally performed.
PWC timer output pin
This pin is available when the PWC2 is output operation.
General-purpose I/O port
This port is available in the single-chip mode or when the upper
address control register setting is “port.”
Output pin for external address bus A23
This pin is available in an external-bus mode and when the upper
address control register setting is “address.”
PWC timer input pin
Since this input is used whenever the PWC3 timer is in input
operation, the output by any other function must be suspended
unless the output is intentionally performed.
