Conditional Search Channel Selection Mask Register
The data in this register controls whether a PIO channel qualifies for participation in the conditional
search command. To include one or more of the PIO channels, the bits in this register that correspond to
those channels need to be set to 1. This register can only be written through the Write Conditional Search
Registers command.
