Setting DCD_EN_ to 1 enables the DC load disconnect
detection feature (Table 17). Setting ACD_EN_ to 1
enables the AC load disconnect feature. If enabled, the
load disconnect detection starts during power mode
and after startup when the corresponding PGOOD_ bit
in register R10h (Table 14) goes high. A reset sets
R13h = 0000AAAAb where A represents the latched-in
state of the AUTO input prior to the reset.

The MAX5965A/MAX5965B use 2 bits for each port to
set the mode of operation. Set the modes according to
Table 16a and 16b.
A reset sets R12h = AAAAAAAAb where A represents
the latched-in state of the AUTO input prior to the reset.
Use software to change the mode of operation.
Software resets of ports (RESET_P_ bit, Table 23) do
not affect the mode register.
