External Match 0. This bit reflects the state of output CT32Bn_MAT0, whether or not this
output is connected to its pin. When a match occurs between the TC and MR0, this bit
can either toggle, go LOW, go HIGH, or do nothing. Bits EMR[5:4] control the
functionality of this output. This bit is driven to the CT32B0_MAT0/CT32B1_MAT0 pins if
the match function is selected in the IOCON registers (0 = LOW, 1 = HIGH).
External Match 1. This bit reflects the state of output CT32Bn_MAT1, whether or not this
output is connected to its pin. When a match occurs between the TC and MR1, this bit
can either toggle, go LOW, go HIGH, or do nothing. Bits EMR[7:6] control the
functionality of this output. This bit is driven to the CT32B0_MAT1/CT32B1_MAT1 pins if
the match function is selected in the IOCON registers (0 = LOW, 1 = HIGH).
External Match 2. This bit reflects the state of output CT32Bn_MAT2, whether or not this
output is connected to its pin. When a match occurs between the TC and MR2, this bit
can either toggle, go LOW, go HIGH, or do nothing. Bits EMR[9:8] control the
functionality of this output. This bit is driven to the CT32B0_MAT2/CT32B1_MAT2 pins if
the match function is selected in the IOCON registers (0 = LOW, 1 = HIGH).
External Match 3. This bit reflects the state of output CT32Bn_MAT3, whether or not this
output is connected to its pin. When a match occurs between the TC and MR3, this bit
can either toggle, go LOW, go HIGH, or do nothing. Bits EMR[11:10] control the
functionality of this output. This bit is driven to the CT32B3_MAT0/CT32B1_MAT3 pins if
the match function is selected in the IOCON registers (0 = LOW, 1 = HIGH).
External Match Control 0. Determines the functionality of External Match 0.
Do Nothing.
Clear the corresponding External Match bit/output to 0 (CT32Bi_MAT0 pin is LOW if
pinned out).
Set the corresponding External Match bit/output to 1 (CT32Bi_MAT0 pin is HIGH if
pinned out).
Toggle the corresponding External Match bit/output.
External Match Control 1. Determines the functionality of External Match 1.
Do Nothing.
Clear the corresponding External Match bit/output to 0 (CT32Bi_MAT1 pin is LOW if
pinned out).
Set the corresponding External Match bit/output to 1 (CT32Bi_MAT1 pin is HIGH if
pinned out).
Toggle the corresponding External Match bit/output.
External Match Control 2. Determines the functionality of External Match 2.
Do Nothing.
Clear the corresponding External Match bit/output to 0 (CT32Bi_MAT2 pin is LOW if
pinned out).
Set the corresponding External Match bit/output to 1 (CT32Bi_MAT2 pin is HIGH if
pinned out).
Toggle the corresponding External Match bit/output.
External Match Control 3. Determines the functionality of External Match 3.
Do Nothing.
Clear the corresponding External Match bit/output to 0 (CT32Bi_MAT3 pin is LOW if
pinned out).
