Description
Software Standby
Specifies transition to software standby mode.
0: Executing SLEEP instruction puts chip into sleep
1: Executing SLEEP instruction puts chip into
Reserved
This bit is always read as 0. The write value should
always be 0. If 1 is written to these bits, correct
operation cannot be guaranteed.
Standby Crystal
Specifies whether the crystal oscillator stops or
continues in standby mode.
0: Stops crystal oscillator in standby mode.
1: Continues crystal oscillator in standby mode.
Reserved
This bit is always read as 0. The write value should
always be 0. If 1 is written to this bit, correct
operation cannot be guaranteed.
Module Stop 2
Halts the clock supply to the timer unit TMU when
the MSTP2 bit has been set to 1.
0: TMU runs
1: Clock supply to TMU halted
Reserved
This bit is always read as 0. The write value should
always be 0. If 1 is written to this bit, correct
operation cannot be guaranteed.
