Conditional Search Channel Polarity Selection Register
The data in this register specifies the polarity of each selected PIO channel for the device to respond to
the conditional search command. Within a PIO channel, the data source may be either the channel's input
signal (pin) or the channel's activity latch, as specified by the PLS bit in the Control/Status register at ad-
dress 008Dh. This register can only be written through the Write Conditional Search Registers command.
