Ответ: (EMR: Timer 0 - T0EMR: 0xE000403C; Timer 1 - T1EMR: 0xE000803C) BIT0 External Match 0 This bit reflects the state of output MAT0/1, whether or not this output is connected to its pin. When a match occurs for MR0, this output of the timer can either toggle, go low, go high, or do nothing. Bits EMR[4:5] control the functionality of this output. RES:0 BIT1 External Match 1 This bit reflects the state of output MAT0/1, whether or not this output is connected to its pin. When a match occurs for MR1, this output of the timer can either toggle, go low, go high, or do nothing. Bits EMR[6:7] control the functionality of this output. RES:0 BIT2 External Match 2 This bit reflects the state of output MAT0/1, whether or not this output is connected to its pin. When a match occurs for MR2, this output of the timer can either toggle, go low, go high, or do nothing. Bits EMR[8:9] control the functionality of this output. RES:0 BIT3 External Match 3 This bit reflects the state of output MAT0/1. When a match occurs for MR3, this output of the timer can either toggle, go low, go high, or do nothing. Bits EMR[10:11] control the functionality of this output. Note: In the case of Timer 0, this output cannot be connected to a device pin. RES:0 BITS 5:4 External Match Control 0 Determines the functionality of External Match 0. Table 112 shows the encoding of these bits. RES:0 BITS 7:6 External Match Control 1 Determines the functionality of External Match 1. Table 112 shows the encoding of these bits. RES:0 BITS 9:8 External Match Control 2 Determines the functionality of External Match 2. Table 112 shows the encoding of these bits. RES:0 BITS 11:10 External Match Control 3 Determines the functionality of External Match 3. Table 112 shows the encoding of these bits. RES:0
