follows:
236
Timer P has a timer synchronized operation function. TMP0 as a master timer and TMP1 to TMP4 as slave timers
Cautions 1. The tuned operation mode is enabled or disabled by the TPnSYE bit of the TPnCTL1 register.
The free-running mode and PWM mode can be used for TMP0 as a master timer in the tuned operation mode as
2. Set the tuned operation mode using the following procedure:
For TMP0, TMP1 to TMP4 can be specified as slaves.
<1> Set the TPnSYE bit of the TPnCTL1 register of the slave timer to enable the tuned
<2> Set the timer mode by using the TPnMD2 to TPnMD0 bits of the TPnCTL1 register. At this
<3> Set the compare register value of the master and slave timers.
<4> Set the TPnCE bit of the TPnCTL0 register of the slave timer to enable operation on the
<5> Set the TPnCE bit of the TPnCTL0 register of the master timer to enable operation on the
