This bit is cleared when the corresponding bit in SCR is written to one.
This bit is set when the SR.CLKBUSY bit has a 1-to-0 transition.
0: The clock is ready and can be changed.
1: CLOCK.CEN has been written and the clock is busy.
This bit is cleared when the corresponding bit in SCR is written to one.
This bit is set when the SR.BUSY bit has a 1-to-0 transition.
0: The AST accepts writes to CR, CV, SCR, WER, EVE, EVD, ARn, PIRn, and DTR.
1: The AST is busy and will discard writes to CR, CV, SCR, WER, EVE, EVD, ARn, PIRn, and DTR.
This bit is cleared when the corresponding bit in SCR is written to one.
This bit is set when the selected bit in the prescaler has a 0-to-1 transition.
This bit is cleared when the corresponding bit in SCR is written to one.
This bit is set when the counter reaches the selected alarm value.
This bit is cleared when the corresponding bit in SCR is written to one.
This bit is set when an overflow has occurred.
