External Match Register. The EMR controls the match function and the external match pins.
| EM0 | External Match 0. This bit reflects the state of output MAT0, whether or not this output is connected to a pin. When a match occurs between the TC and MR0, this bit can either toggle, go LOW, go HIGH, or do nothing, as selected by EMR[5:4]. This bit is driven to the MAT pins if the match function is selected via IOCON. 0 = LOW. 1 = HIGH. |
| EM1 | External Match 1. This bit reflects the state of output MAT1, whether or not this output is connected to a pin. When a match occurs between the TC and MR1, this bit can either toggle, go LOW, go HIGH, or do nothing, as selected by EMR[7:6]. This bit is driven to the MAT pins if the match function is selected via IOCON. 0 = LOW. 1 = HIGH. |
| EM2 | External Match 2. This bit reflects the state of output MAT2, whether or not this output is connected to a pin. When a match occurs between the TC and MR2, this bit can either toggle, go LOW, go HIGH, or do nothing, as selected by EMR[9:8]. This bit is driven to the MAT pins if the match function is selected via IOCON. 0 = LOW. 1 = HIGH. |
| EM3 | External Match 3. This bit reflects the state of output MAT3, whether or not this output is connected to a pin. When a match occurs between the TC and MR3, this bit can either toggle, go LOW, go HIGH, or do nothing, as selected by MR[11:10]. This bit is driven to the MAT pins if the match function is selected via IOCON. 0 = LOW. 1 = HIGH. |
| EMC0 | External Match Control 0. Determines the functionality of External Match 0. 0 (DO_NOTHING): Do Nothing. 1 (CLEAR): Clear. Clear the corresponding External Match bit/output to 0 (MAT0 pin is LOW if pinned out). 2 (SET): Set. Set the corresponding External Match bit/output to 1 (MAT0 pin is HIGH if pinned out). 3 (TOGGLE): Toggle. Toggle the corresponding External Match bit/output. |
| EMC1 | External Match Control 1. Determines the functionality of External Match 1. 0 (DO_NOTHING): Do Nothing. 1 (CLEAR): Clear. Clear the corresponding External Match bit/output to 0 (MAT1 pin is LOW if pinned out). 2 (SET): Set. Set the corresponding External Match bit/output to 1 (MAT1 pin is HIGH if pinned out). 3 (TOGGLE): Toggle. Toggle the corresponding External Match bit/output. |
| EMC2 | External Match Control 2. Determines the functionality of External Match 2. 0 (DO_NOTHING): Do Nothing. 1 (CLEAR): Clear.
