Mode Control
CONFIG - Configuration-control input, PIN 11Q, 17L
CONFIG is used in conjunction with other configuration-control pins to control operating mode
(see Table 2). Serial data is 16-bits long in Mode 2 if CONFIG is high, 8-bits if CONFIG is
low.
SCLK_RATE0 - SCLK frequency control, PIN 29Q, 35L
Used in conjunction with SCLK_RATE1 to set the SCLK frequency when the CS6403 is a
timing slave. Possible frequencies are 2.048 MHz, 1.024 MHz, and 256 kHz, for
SCLK_RATE1:SCLK_RATE0 being 11, 10, and 00, respectively. However, if the CS6403 is a
timing master (i.e., SMASTER is high), the SCLK frequency may only be 2.048 MHz, so in
this case, SCLK_RATE0 must be high.
SCLK_RATE1 - SCLK frequency control, PIN 30Q, 36L
Used in conjunction with SCLK_RATE0 to set the SCLK frequency when the CS6403 is a
timing slave. Possible frequencies are 2.048 MHz, 1.024 MHz, and 256 kHz, for
SCLK_RATE1:SCLK_RATE0 being 11, 10, and 00, respectively. However, if the CS6403 is a
timing master (i.e., SMASTER is high), the SCLK frequency may only be 2.048 MHz, so in
this case, SCLK_RATE1 must be high.
SFRAME - SSYNC frame/pulse control, PIN 1Q, 7L
If SFRAME is high, SYNCOUT is high during serial data transactions. If SFRAME is low,
SYNCOUT is pulsed high for one SCLK period before the start of a serial-data transaction.
