7.6 Timer-Tuned Operation Function
Timer AA and timer AB have a timer-tuned operation function.
The timer-tuned operation function is used to tune the internal timers of the V850ES/JG3-H and V850ES/JH3-H, so that
the number of capture or compare registers of the slave timer (the number of timer outputs and the number of compare
match interrupts of the slave timer) can be added to the master timer. The timers that can be tuned are listed in Table 7-7.

Master Timer Slave Timer
TAA1 TAA0
TAA3 TAA2
TAB0 TAA5
The tuned-operation function has the following modes.
• PWM output mode
• Free-running timer mode
Figure 7-43 shows an example where individual operation and tuned operation of TAA0 (as the master timer) and TAA1
(as the slave timer) are performed in PWM output mode.

Two PWM outputs are available when PWM
is operated separately with each timer.
