AD8197
PARALLEL CONTROL INTERFACE
The AD8197 can be controlled through the parallel interface
using the PP_EN, PP_CH[1:0], PP_EQ, PP_PRE[1:0], PP_OTO,
and PP_OCL pins. Logic levels for the parallel interface pins
are set in accordance with the specifications listed in Table 1.
Setting these pins updates the parallel control interface
registers, as listed in Table 24. Following a reset, the AD8197

can be controlled through the parallel control interface until the
first serial control event occurs. As soon as any serial control
event occurs, the serial programming values override any prior
parallel programming values, and the parallel control interface
is disabled until the part is subsequently reset. The default serial
programming values correspond to the state of the serial
interface configuration registers, as listed in Table 5.
