WebDec 15, 2016 · Our timer/blinking light example is going to use the MSP430’s Timer A0 (TA0) with the ACLK as its input clock. ACLK runs at 32768 Hz. We’ll configure both input dividers into TA0 as divide-by-1, so TA0 will run at the same frequency as ACLK, which is 32768 Hz. We’ll configure TA0 in continuous mode, which means it will repeatedly count ... WebWhen a timer has a chain mode enabled, it only counts after the previous timer has expired. If the timer n-1 has counted down to 0, counter n decrements the value by one. Each timer is 32-bits, which allows the developers to chain timers together and form a longer timer (64-bits and larger). eastgate house longton
