CS1- I This chip select is used to access the Alternate Status Register

and the Device Control Register.

DASP- I/O This input/output is the Device Active/Slave Present signal in the

master/slave handshake protocol.

DEVADR I When driven low (Gnd) the P4 will respond as Master Device.

When pulled high (+3.3V) the P4 will respond as Slave Device.
