The data in this register specifies the polarity of each selected PIO channel for the device to respond to the
conditional search command. This register can only be written through the Write Registers command. Within a PIO
channel, the data source may be either the channel's input pin or the channel's activity latch, as specified by the
PLS bit in the Control/Status register at address 0225h. This register is read/write. Each bit is associated with the
respective PIO channel as shown in Figure 7. Bits 2 to 7 have no function; they always read 0 and cannot be
changed to 1. This register is cleared to 00h at power-up.

The data in this register reports status information and further configures the device for conditional search. This
register can only be written through the Write Registers command. This register is read/write. The power-up state
of the PORL bit is "1". CT and PLS power up as "0". The functional assignments of the individual bits are explained
in the table below. Bits 2, 4, and 5 have no function; they always read 0 and cannot be set to 1.

DEFINITION
Selects either the PIO pins or the PIO activity latches as input for the
conditional search.
0: pin selected (default)
1: activity latch selected
Specifies whether the data of two channels needs to be ORed or
AND’ed to meet the qualifying condition for the device to respond to
a conditional search. If only a single channel is selected in the
channel selection mask (0223h) this bit is a don't care.
0: bitwise OR (default)
1: bitwise AND
Specifies whether the device has performed a power-on reset. This
bit can only be cleared to 0 by writing to the Control/Status Register.
As long as this bit is 1 the device will always respond to a Conditional
Search ROM sequence.
Reports the state of the POL pin. The state of the POL pin specifies
whether the PIO pins P0 and P1 power up high or low. The polarity
of a pulse generated at a PIO pin is the opposite of the pin's power-
up state.
0: PIO powers up 0
1: PIO powers up 1
For V CC -powered operation, the V CC pin needs to be connected to a
voltage source equal to V PUP .
0: V CC power not available
1: V CC -powered operation
