・ fc = 32MHz / 9.8304MHz / 8MHz
・ fgear = 32MHz / 9.8304MHz / 8MHz (CGSYSCR<GEAR[2:0]> = "000" : fc selected)
・ ΦT0 = 16MHz / 4.9152MHz / 4MHz (CGSYSCR<PRCK[2:0]> = "001" : 2 division
・ Timer count clock = 4MHz / 1.2287MHz / 1MHz (TBxMOD<TBCLK[1:0]> = "01" :
To enable the timer output, the following condition must be set: a timer flip-flop output
Baud rates can be obtained by using the following formula.
