REVE
RSE
0: count forward; 1: count backwards.
Only changes when ENABLE bit is set to ‘0’.
0: disable sleep timer; 1: enable sleep timer.
To change other register bits (REVERSE, CLK_DIV, CLK_SEL), this bit must be set to ‘0’.
Enabling/Disabling latency can be up 2 to 3 clock-periods of selected clock.
0: The timer continues working in Debug mode.
1: The timer is paused in Debug mode when the CPU is halted.
Divides clock by 2
Can only be changed when the ENABLE bit is set to ‘0’.
0: Calibrated 1kHz RC clock (default); 1: 32kHz
Can only be changed when the ENABLE bit is set to ‘0’.
