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 Timer B Prescale
The register loads this value on a write. A read returns the current value
of this register.
Refer to Table 10-6 on page 471 for more details and an example.
