Timer Mode High Bit
This bit along with TMODE[2:0] field in T0CTL1 register determines the
operating mode of the timer. This is the most significant bit of the timer mode
selection value. For more details, see the T0CTL1 register description.
Timer Interrupt Configuration—This field configures timer
interrupt definitions.
These bits affect all modes. The effect per mode is explained below:
ONE SHOT, CONTINUOUS, COUNTER, PWM, COMPARE, DUAL PWM,
TRIGGERED ONE-SHOT, COMPARATOR COUNTER:
0x Timer interrupt occurs on reload.
10 Timer interrupts are disabled.
11 Timer Interrupt occurs on reload.
GATED:
0x Timer interrupt occurs on reload.
10 Timer interrupt occurs on inactive gate edge.
11 Timer interrupt occurs on reload.
CAPTURE, CAPTURE/COMPARE, CAPTURE RESTART:
0x Timer interrupt occurs on reload and capture.
10 Timer interrupt occurs on capture only.
11 Timer interrupt occurs on reload only.
Timer cascade—This field allows the timers to be cascaded for larger
counts.
The timer is not cascaded.
Timer is cascaded. If timer 0 CASCADE bit is set, COMPARATOR output is
used as input. If timer 1 CASCADE bit is set, the Timer 0 output is used as the
input. If timer 2 CASCADE bit is set, the timer 1 output is used as input.
PWM Delay Value
This field is a programmable delay to control the number of additional system
clock cycles following a PWM or Reload compare before the timer output or
the timer output complement is switched to the active state. This field ensures
a time gap between deassertion of one PWM output to the assertion of its
complement.
No delay.
2 cycles delay.
4 cycles delay.
8 cycles delay.
16 cycles delay.
32 cycles delay.
64 cycles delay.
128 cycles delay.
