tions of GPIO_DATA_REG when it detects regis-
ter address 0×0A through the IC interface. A
detection of address 0×0A can happen in two ways.
The first and most common way this will happen is
when address 0×0A is written to the CS4954/5 via
its IC interface. The second method for detecting
address 0×0A is implemented by accessing register
address 0×09 through IC. In IC host interface op-
eration, the CS4954/5 register address pointer will
auto-increment to address 0×0A after an address
0×09 access.
The GPIO port PDAT [7:0] pins are configured for
output
operation
when
the
corresponding
GPIO_CTRL_REG [7:0] bits are set. In GPIO out-
put mode, the CS4954/5 will output the data in
GPIO_DATA_REG [7:0] bit locations onto the
corresponding PDAT [7:0] pins when it detects a
register address 0×0A through the IC interface.
