Channel Status Register
Name:
SR
Access Type:
Read-only
Offset:
0x20 + n * 0x40
Reset Value:
0x00000000
Note: Reading the Status Register will also clear the interrupt bit for the corresponding interrupts.
MTIOB: TIOB Mirror
1: TIOB is high. If CMRn.WAVE is zero, this means that TIOB pin is high. If CMRn.WAVE is one, this means that TIOB is driven
high.
0: TIOB is low. If CMRn.WAVE is zero, this means that TIOB pin is low. If CMRn.WAVE is one, this means that TIOB is driven
low.
MTIOA: TIOA Mirror
1: TIOA is high. If CMRn.WAVE is zero, this means that TIOA pin is high. If CMRn.WAVE is one, this means that TIOA is driven
high.
0: TIOA is low. If CMRn.WAVE is zero, this means that TIOA pin is low. If CMRn.WAVE is one, this means that TIOA is driven
low.
CLKSTA: Clock Enabling Status
1: This bit is set when the clock is enabled.
0: This bit is cleared when the clock is disabled.
ETRGS: External Trigger Status
1: This bit is set when an external trigger has occurred.
0: This bit is cleared when the SR register is read.
LDRBS: RB Loading Status
1: This bit is set when an RB Load has occurred and CMRn.WAVE is zero.
0: This bit is cleared when the SR register is read.
LDRAS: RA Loading Status
1: This bit is set when an RA Load has occurred and CMRn.WAVE is zero.
0: This bit is cleared when the SR register is read.
CPCS: RC Compare Status
1: This bit is set when an RC Compare has occurred.
0: This bit is cleared when the SR register is read.
