Description

PLL0 Status Register

Fields

MSEL0

Read-back for the PLL0 Multiplier value. This is the value currently used by PLL0, and is one less than the actual multiplier.

RESERVED

Reserved, user software should not write ones to reserved bits. The value read from a reserved bit is not defined.

NSEL0

Read-back for the PLL0 Pre-Divider value. This is the value currently used by PLL0, and is one less than the actual divider.

PLLE0_STAT

Read-back for the PLL0 Enable bit. This bit reflects the state of the PLEC0 bit in PLL0CON after a valid PLL0 feed. When one, PLL0 is currently enabled. When zero, PLL0 is turned off. This bit is automatically cleared when Power-down mode is entered.

PLLC0_STAT

Read-back for the PLL0 Connect bit. This bit reflects the state of the PLLC0 bit in PLL0CON after a valid PLL0 feed. When PLLC0 and PLLE0 are both one, PLL0 is connected as the clock source for the CPU. When either PLLC0 or PLLE0 is zero, PLL0 is bypassed. This bit is automatically cleared when Power-down mode is entered.

PLOCK0

Reflects the PLL0 Lock status. When zero, PLL0 is not locked. When one, PLL0 is locked onto the requested frequency. See text for details.

RESERVED

Reserved, user software should not write ones to reserved bits. The value read from a reserved bit is not defined.
