Functional Description
The main components of each GPTM block are two free-running up/down counters (referred to as
Timer A and Timer B), two prescaler registers, two match registers, two prescaler match registers,
two shadow registers, and two load/initialization registers and their associated control functions.
The exact functionality of each GPTM is controlled by software and configured through the register
interface. Timer A and Timer B can be used individually, in which case they have a 16-bit counting
range for the 16/32-bit GPTM blocks and a 32-bit counting range for 32/64-bit Wide GPTM blocks.
In addition, Timer A and Timer B can be concatenated to provide a 32-bit counting range for the
16/32-bit GPTM blocks and a 64-bit counting range for the 32/64-bit Wide GPTM blocks. Note that
the prescaler can only be used when the timers are used individually.
The available modes for each GPTM block are shown in Table 10-3 on page 650. Note that when
counting down in one-shot or periodic modes, the prescaler acts as a true prescaler and contains
