a. The TTL designation indicates the pin has TTL-compatible voltage levels.
10.3 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 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. In addition, Timer
A and Timer B can be concatenated to provide a 32-bit counting range. Note that the prescaler can
only be used when the timers are used individually.
