Sleep timer count high register (SLPTMR_CNTH)

Address:

0x4000 6010

Reset value:

0x0000 0000

Reserved, must be kept at reset value

CNTH[15:0]: Sleep timer counter high value

Bit 10 DBGP: Debug pause

0: The timer continues working in Debug mode.

1: The timer is paused in Debug mode when the CPU is halted.

Bits [9:8] Reserved, must be kept at reset value

Bits [7:4] PSC[3:0]: Sleep timer prescaler setting

Divides clock by 2N where N = 0 to 15.

Can only be changed when the EN is set to ‘0’.

Bits [3:1] Reserved, must be kept at reset value

Bit 0 CLKSEL: Clock select

0: Calibrated 1kHz RC clock (default); 1: 32kHz.

Can only be changed when the EN is set to ‘0’.

Reserved

CNTH[15:0]
