Generating interrupts at periodic cycles
To generate the INTTB0 interrupt, specify a time interval in the TB0RG1 timer register.
By using an input clock as an external clock (TB1IN0 pin input), it is possible to make it the event
counter.
The up-counter counts up on the rising edge of TB1IN0 pin input. By capturing a value using software
and reading the captured value, it is possible to read the count value.

X; Don't care −; no change
X; Don't care −; no change
To be used as the event counter, put the prescaler in a "RUN" state
(TB1RUN<TB1PRUN> = "1").

Starts the TMRB0 module.
Stops TMRB0.
Enables INTTB0, and sets it to level 4.
(Setting of INTTB0 only is shown here. This is a 32-bit
register and requires settings of other interrupts as well.)
Disables the trigger.
Designates the prescaler input clock as the output clock,
and specifies the time interval.
(16 bits * This is a 32-bit register.)
Starts TMRB0.
Starts the TMRB0 module.
Stops TMRB1.
Sets P20 to the input mode.
Enables INTTB0, and sets it to level 4.
(Setting of INTTB0 only is shown here. This is a 32-bit
register and requires settings of other interrupts as well.)
Disables the trigger.
Designates the TB1IN0 pin input as the input clock.
Starts TMRB1.
Captures a value using software.
Specifies the time interval.
