Software resets of ports (RESET_P_ bit, Table 22) do
not affect the mode register.
Setting DCD_EN_ to 1 enables the DC load disconnect
detection feature (Table 16). 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 13) goes high. A Reset sets
R13h = 0000AAAA where A represents the latched-in
state of the AUTO input prior to the reset.
Setting DET_EN_/CLASS_EN_ to 1 (Table 17) enables
load detection/classification, respectively. Detection
always has priority over classification. To perform clas-
sification without detection, set the DET_EN_ bit low
and CLASS_EN_ bit high.
