7.1.6. Timer Interrupt and Flag Setting Timing
Timer interrupt occurs when the serial timer register (STMR) and the serial timer comparison register
(STMCR) are matched.
⋅
When the serial timer register (STMR) and the serial timer comparison register are matched, the timer
interrupt flag (SACSR:TINT) is set to "1".
If the timer interrupt is enabled (SACSR:TINTE="1") at this time, a status interrupt occurs.
