PCLK[4:3] — Pulse-Width Channel 4, 3 Clock Select Bits
PCLK[2:1] — Pulse-Width Channel 2, 1 Clock Select Bits
PPOL[4:1] — Pulse-Width Channel x Polarity Bits
Scaled clock S is generated by dividing clock A by the value in PWSCAL,
then dividing the result by two. If PWSCAL = $00, the divisor is 256, then
two.
