6.11 External Match Register (T[0/1/2/3]EMR - 0xE000 403C, 0xE000 803C,
0xE007 003C, 0xE007 403C)
The External Match Register provides both control and status of the external match pins.
In the descriptions below, “n” represents the Timer number, 0,1, 2, or 3, and “m” represent
a Match number, 0 through 3.

External Match 0. When a match occurs between the TC and MR0, this
bit can either toggle, go low, go high, or do nothing, depending on bits 5:4
of this register. This bit can be driven onto a MATn.0 pin, in a
positive-logic manner (0 = low, 1 = high).
External Match 1. When a match occurs between the TC and MR1, this
bit can either toggle, go low, go high, or do nothing, depending on bits 7:6
of this register. This bit can be driven onto a MATn.1 pin, in a
positive-logic manner (0 = low, 1 = high).
External Match 2. When a match occurs between the TC and MR2, this
bit can either toggle, go low, go high, or do nothing, depending on bits 9:8
of this register. This bit can be driven onto a MATn.0 pin, in a
positive-logic manner (0 = low, 1 = high).
External Match 3. When a match occurs between the TC and MR3, this
bit can either toggle, go low, go high, or do nothing, depending on bits
11:10 of this register. This bit can be driven onto a MATn.0 pin, in a
positive-logic manner (0 = low, 1 = high).
External Match Control 0. Determines the functionality of External Match
0.
External Match Control 1. Determines the functionality of External Match
1.
External Match Control 2. Determines the functionality of External Match
2.
External Match Control 3. Determines the functionality of External Match
3.
Reserved, user software should not write ones to reserved bits. The
value read from a reserved bit is not defined.

Function
Do Nothing.
Clear the corresponding External Match bit/output to 0 (MATn.m pin is
LOW if pinned out).
Set the corresponding External Match bit/output to 1 (MATn.m pin is
HIGH if pinned out).
Toggle the corresponding External Match bit/output.
