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.
Sleep with PLL
The value in this field is the suggested value for the VLDO field in the
LDOSPCTL register when using the PLL. This value provides the lowest
recommended LDO output voltage for use with the PLL at the maximum
specified value.
Sleep without PLL
The value in this field is the suggested value for the VLDO field in the
LDOSPCTL register when not using the PLL. This value provides the
lowest recommended LDO output voltage for use without the PLL.
