Low-Power, Multifunction, Polyphase AFE
This register selects which phases are included in the CFQ pulse output and also selects which quantity is accumu-
lated to drive the pulse output.
This register designates the width of the CFP pulse, that is, the duration of the period that the CFP pulse is in the
active state. This value is given in ADC frame times (about 320μs). The default value of 0x9C (156 decimal) provides
a pulse width of about 50ms.
