The pulse accumulator counter register reflect the number of pulses from the divided-by-64 clock since the
last reset.
16.5
The reset state of each individual bit is listed within
which details the registers and their bit fields.
16.6
This section describes interrupts originated by the TIM16B8CV2 block.
generated by the TIM16B8CV2 to communicate with the MCU.
The TIM16B8CV2 uses a total of 11 interrupt vectors. The interrupt vector offsets and interrupt numbers
are chip dependent.
16.6.1
This active high outputs will be asserted by the module to request a timer channel 7 – 0 interrupt to be
serviced by the system controller.
16.6.2
This active high output will be asserted by the module to request a timer pulse accumulator input interrupt
to be serviced by the system controller.
16.6.3
This active high output will be asserted by the module to request a timer pulse accumulator overflow
interrupt to be serviced by the system controller.

The timer prescaler generates the divided-by-64 clock. If the timer is not
active, there is no divided-by-64 clock.
