PARALLEL CONTROL INTERFACE
The AD8191A 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 18. Following a reset, the AD8191A 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.
Note that after changing the status of the channel selection
(PP_CH[1:0]), it is necessary to assert a low logic level to RESET
RESET to ensure that the channel select status is properly updated.
