Bit 2—CS4 Enable (CS4E): Enables or disables host interface channel 4 functions in slave mode.
When these functions are enabled, channel 4 pins are enabled and processing can be performed for
data transfer between the slave and the host processors.
Bit 1—CS3 Enable (CS3E): Enables or disables host interface channel 3 functions in slave mode.
When these functions are enabled, channel 3 pins are enabled and processing can be performed for
data transfer between the slave and the host processors.
Bit 0—Host Interface Enable Bit (HI12E): Enables or disables host interface functions in
single-chip mode. When the host interface functions are enabled, processing is performed for data
transfer between the slave and the host processors using the pins determined by bits CS2E to
CS4E, FGA20E, and SDE.
