Bits 7:6 Reserved

Bits 5:0 APR[5:0]: Asynchronous prescaler divider

These bits are written by software to select the prescaler divider (APRDIV) feeding the counter clock.

0x00: APRDIV = 2 0x0E: APRDIV = 16

0x01: APRDIV = 3 0x0F: APRDIV = 17

... ...

0x06: APRDIV = 8 0x3E: APRDIV = 64

Note: This register must not be kept at its reset value (0x3F)

AWUTB[3:0]

Bits 7:4 Reserved

Bits 3:0 AWUTB[3:0]: Auto-wakeup timebase selection

These bits are written by software to define the time interval between AWU interrupts. AWU

interrupts are enabled when AWUEN = 1.
