Register 14: GPTM Timer A Prescale (GPTMTAPR), offset 0x038
This register allows software to extend the range of the timers when they are used individually.
When in one-shot or periodic down count modes, this register acts as a true prescaler for the timer
counter. When acting as a true prescaler, the prescaler counts down to 0 before the value in the
GPTMTAR and GPTMTAV registers are incremented. In all other individual/split modes, this register
is a linear extension of the upper range of the timer counter, holding bits 23:16 in the 16-bit modes
of the 16/32-bit GPTM.

Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.

GPTM Timer A Prescale
The register loads this value on a write. A read returns the current value
of the register.
For the 16/32-bit GPTM, this field contains the entire 8-bit prescaler.
Refer to Table 13-5 on page 961 for more details and an example.
