Section 14 16-Bit Timer Pulse
Unit (TPU)
14.3.6 Timer Counter (TCNT)
285 Deleted
TCNT is a 16-bit readable/writable counter. The TPU has a total
of two TCNT counters, one for each channel.
TCNT is initialized to H'0000 by a reset or in har
dware standby
mode.

Mask levels within a channel can be changed by the interrupt
controller. For details, see section 4, Interrupt Controller.
14.8.12 Interrupts when Module
Standby Function is Used
318 Modified
If the module standby function is used when an interrupt has
been requested, it will not be possible to clear the CPU interrupt
source with the interrupt request enabled. Interrupts should
therefore be disabled before using the module standby function.

Notes:
1. When an asynchronous external event is input, the counter
increments. In addition, when an overflow occurs, an interrupt
is requested.
