To obtain the frequency 62.5 kHz, the pulse cycle t should be: t = 1/62.5 kHz = 16 µs. Given φT1 = 0.4 µs (at 20 MHz), 16 µs ÷ 0.4 µs = 40 Consequently, to set the timer register 3 (TREG3) to TREG3 = 40 = 28H and then duty to 1/4, t × 1/4 = 16 µs × 1/4 = 4 µs 4 µs ÷ 0.4 µs = 10 Therefore, set timer register 2 (TREG2) to TREG2 = 10 = 0AH. 7 6 5 4 3 2 1 0 TRUN ← − X − − 0 0 −− Stop timer 2, 3 and clear it to “0”. T32MOD ← 1 0 X X X X 0 1 Set the 8-bit PPG mode, and select φT1 as input clock. TREG2 ← 0 0 0 0 1 0 1 0 Write “0AH”. TREG3 ← 0 0 1 0 1 0 0 0 Write “28H”. TFFCR ← 0 1 1 X − − − − Sets TFF3 and enable the inversion and double buffer enable. Writing “10” provides negative logic pulse. P4CR ← X X X X − − 1 − P4FC ← X X X X − − 1X Set P41 as the TO3 pin. TRUN ← 1 X − − 1 1 −− Start timer 2 and timer 3 counting. X: Don’t care −: No change 16 µs |
