This register controls panel power on/off sequencing delays. The generation of the clock for the panel
power sequencing logic is controlled by XRCF bit 3. The delay intervals above assume a 37.5 KHz clock
generated by the 14.31818 MHz reference clock. If using a 32KHz input, scale the delay intervals
accordingly.

Power Up Delay
Programmable value of panel power sequencing during power up. This value can be programmed
up to 54 milliseconds in increments of 3.4 milliseconds. A value of 0 is undefined.
Power Down Delay
Programmable value of panel power-sequencing during power down. This value can be
programmed up to 459 milliseconds in increments of 27.5 milliseconds. A value 0 is undefined.
