Setting Range RW
If setting value is n, the timer stops when the nth count
source is counted after a start trigger is generated.
Positive phase changes to negative phase, and vice

versa, when the timers A1, A2 and A4 stop.
NOTES:
1. Use a 16-bit data for read and write.
2. If the TAi or TAi1 register is set to "0000h", no counters start and no timer Ai interrupt is generated.
3. Use the MOV instruction to set the TAi and TAi1 registers.
4. When the INV15 bit in the INVC1 register is set to "0" (dead timer enabled), phase switches from an
inactive level to an active level when the dead time timer stops.
5. When the INV11 bit in the INVC1 register is set to "0" (three-phase mode 0), the value of the TAi register
is transferred to the reload register by a timer Ai start trigger.
When the INV11 bit is set to "1" (three-phase mode 1), the value of the TAi1 register is first transferred to
the reload register by a timer Ai start trigger. Then, the value of the TAi register is transferred by the next
trigger. The values of the TAi1 and TAi registers are transferred alternately to the reload register with every
timer Ai start trigger.
6. Do not write to these registers when the timer B2 underflows.
7. Follow the procedure below to set the TAi1 register.
(a) Write value to the TAi1 register,
(b) Wait one timer Ai count source cycle, and
(c) Write the same value as (a) to the TAi1 register.

Setting Range _RW
If setting value is n, count source is divided by n+1.
