Timer 3 Compare Mode Register 1 (T3CM1)
Address: ’B’hex – Subaddress: ’2’hex
Bit 3
Bit 2
Bit 1
Bit 0
T3CM1
T3SM1
T3TM1
T3RM1
T3IM1
Reset value: 0000b
T3SM1
Timer 3 Single action Mask bit 1
T3SM1 = 0, disables single-action compare mode
T3SM1 = 1, enables single-compare mode. After this bit is set, the compare register (T3CO1) is
used until the next compare match.
T3TM1
Timer 3 compare Toggle action Mask bit 1
T3TM1 = 0, disables compare toggle
T3TM1 = 1, enables compare toggle. A match of Counter 3 with the compare register
(T3CO1) toggles the output flip-flop (TOG3).
T3RM1
Timer 3 Reset Mask bit 1
T3RM1 = 0, disables counter reset
T3RM1 = 1, enables counter reset. A match of Counter 3 with the compare register (T3CO1)
resets the Counter 3.
T3IM1
Timer 3 Interrupt Mask bit 1
T3RM1 = 0, disables Timer 3 interrupt for T3CO1 register.
T3RM1 = 1, enables Timer 3 interrupt for T3CO1 register.
T3CM1 contains the mask bits for the match event of the Counter 3 compare register 1
Timer 3 Compare Mode Register 2 (T3CM2)
Address: ’B’hex – Subaddress: ’3’hex
Bit 3
Bit 2
Bit 1
Bit 0
T3CM2
T3SM2
T3TM2
T3RM2
T3IM2
Reset value: 0000b
T3SM2
Timer 3 Single action Mask bit 2
T3SM2 = 0, disables single-action compare mode
T3SM2 = 1, enables single-compare mode. After this bit is set, the compare register (T3CO2) is
used until the next compare match.
T3TM2
Timer 3 compare Toggle action Mask bit 2
T3TM2 = 0, disables compare toggle
T3TM2 = 1, enables compare toggle. A match of Counter 3 with the compare register
(T3CO2) toggles the output flip-flop (TOG3).
T3RM2
Timer 3 Reset Mask bit 2
T3RM2 = 0, disables counter reset
T3RM2 = 1, enables counter reset. A match of Counter 3 with the compare register (T3CO2)
resets the Counter 3.
T3IM2
Timer 3 Interrupt Mask bit 2
T3RM2 = 0, disables Timer 3 interrupt for T3CO2 register.
T3RM2 = 1, enables Timer 3 interrupt for T3CO2 register.
T3CM2 contains the mask bits for the match event of Counter 3 compare register 2
The compare registers and corresponding counter reset masks can be used to program the counter time intervals and
the toggle masks can be used to program output signal. The single-action mask can also be used in this mode. It starts
operating after the timer started with T3R.
