Prescale value
The timer input clock is divided by 2
reset each time the Timer is disabled. This reset ensures proper clock division each time the
Timer is restarted.
000 = Divide by 1.
001 = Divide by 2.
010 = Divide by 4.
011 = Divide by 8.
100 = Divide by 16.
101 = Divide by 32.
110 = Divide by 64.
111 = Divide by 128.
Timer Mode
This field, along with the TMODEHI bit in the TxCTL0 Register, determines the operating mode
of the timer. TMODEHI is the most significant bit of the Timer mode selection value. The entire
operating mode bits are expressed as {TMODEHI, TMODE[2:0]}. The TMODEHI is bit 7 of the
TxCTL0 Register while TMODE[2:0] is the lower 3 bits of the TxCTL1 Register.
0000 = ONE-SHOT Mode.
0001 = CONTINUOUS Mode.
0010 = COUNTER Mode.
0011 = PWM SINGLE OUTPUT Mode.
0100 = CAPTURE Mode.
0101 = COMPARE Mode.
0110 = GATED Mode.
0111 = CAPTURE/COMPARE Mode.
1000 = PWM DUAL OUTPUT Mode.
1001 = CAPTURE RESTART Mode.
1010 = COMPARATOR COUNTER Mode.
The Timer 0–1 High and Low Byte (TxH and TxL) registers, shown in Tables 52 and 53,
contain the current 16-bit timer count value. When the timer is enabled, a read from TxH
causes the value in TxL to be stored in a temporary holding register. A read from TxL
always returns this temporary register when the timers are enabled. When the timer is dis-
abled, reads from TxL read the register directly.
Writing to the Timer High and Low Byte registers while the timer is enabled is not recom-
mended. There are no temporary holding registers available for write operations, so simul-
taneous 16-bit writes are not possible. If either the Timer High or Low Byte registers are
written during counting, the 8-bit written value is placed in the counter (High or Low
Byte) at the next clock edge. The counter continues counting from the new value.
