Control and status register
Direct access to the PWM counter
INT and FRAC form a fixed-point fractional number. Counting rate is system clock frequency divided by this number. Fractional division uses simple 1st-order sigma-delta.
Counter wrap value
This register aliases the CSR_EN bits for all channels. Writing to this register allows multiple channels to be enabled or disabled simultaneously, so they can run in perfect sync. For each channel, there is only one physical EN register bit, which can be accessed through here or CHx_CSR.
