Description

PLL1 Status Register

Fields

MSEL1

Read-back for the PLL1 Multiplier value. This is the value currently used by PLL1.

PSEL1

Read-back for the PLL1 Divider value. This is the value currently used by PLL1.

RESERVED

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

PLLE1_STAT

Read-back for the PLL1 Enable bit. When one, PLL1 is currently activated. When zero, PLL1 is turned off. This bit is automatically cleared when Power-down mode is activated.

PLLC1_STAT

Read-back for the PLL1 Connect bit. When PLLC and PLLE are both one, PLL1 is connected as the clock source for the microcontroller. When either PLLC or PLLE is zero, PLL1 is bypassed and the oscillator clock is used directly by the microcontroller. This bit is automatically cleared when Power-down mode is activated.

PLOCK1

Reflects the PLL1 Lock status. When zero, PLL1 is not locked. When one, PLL1 is locked onto the requested frequency.

RESERVED

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