Description
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 TimerA Prescale
The register loads this value on a write. A read returns the current value
of the register.
Refer to Table 8-3 on page 276 for more details and an example.
