• Manufacturer: SyncMOS Technologies,Inc

If user use Fosc=20MHz, SPFS[1:0] of SPWMC=#03H, then
SPWM clock = 20MHz/2^4 = 20MHz/16 = 1.25MHz
SPWM output cycle frame frequency = (20MHz/2^4)/32=39.1KHz
7. TWSI Interface (Two Wire Serial Interface)

(narrow pulse inserted by BRM0[2:0] setting, here BRM0[2:0]=3)
SPWM clock = 1 / T = Fosc / 2^(SPFS[1:0]+1)
The SPWM output cycle frame frequency = SPWM clock / 32 = [Fosc/2^(SPFS[1:0]+1)]/32
with 128KB flash & 1KB RAM & TWSI & SPWM embedded
