T13 Shadow Register Transfer
A special shadow transfer signal (T13_ST) can be generated to facilitate updating the period and compare
values of the compare channel CC63 synchronously to the operation of T13. Providing a shadow register for
values defining one PWM period facilitates a concurrent update by software for all relevant parameters. The
next PWM period can run with a new set of parameters. The generation of this signal is requested by software
via bit TCTR0.STE13 (set by writing 1 to the write-only bit TCTR4.T13STR, cleared by writing 1 to the write-only
bit TCTR4.T13STD).
When signal T13_ST is active, a shadow register transfer is triggered with the next cycle of the T13 clock. Bit
STE13 is automatically cleared with the shadow register transfer. A T13 shadow register transfer takes place
(T13_ST active):
• while timer T13 is not running (T13R = 0), or
• STE13 = 1 and a Period-Match is detected while T13R = 1
