Number of divided clock cycles in the entire period of the PWM waveform, minus 1. For example, to obtain
6 clock cycles in the actual period, set this field to 5.
Fixed read-only value reflecting the MAJOR field of the RTL version.
Fixed read-only value reflecting the MINOR field of the RTL version.
Fixed read-only value reflecting the stepping of the RTL version.

DIV_256 — Divide by 256.
DIV_1024 — Divide by 1024.
HI_Z — Inactive state sets PWM output to high-impedance.
0 — Inactive state sets PWM output to 0 (low).
1 — Inactive state sets PWM output to 1 (high).
HI_Z — Active state sets PWM output to high-impedance.
0 — Active state sets PWM output to 0 (low).
1 — Active state sets PWM output to 1 (high).
