11-11
11.3.4.1
RCCR_1 Rx High Freq. Clock Divider (RFP3-RFP0) - Bits 14–17
Since the ESAI_1 does not have the receiver high frequency clock pin, the RFP3–RFP0 bits
simply specify an additional division ratio in the clock divider chain. See Figure 11-4.
11.3.4.2
RCCR_1 Rx High Freq. Clock Polarity (RHCKP) - Bit 20
The ESAI_1 does not have the receiver high frequency clock pin. It it recommended that
RHCKP should be kept cleared.
11.3.4.3
RCCR_1 Rx High Freq. Clock Direction (RHCKD) - Bit 23
The ESAI_1 does not have the receiver high frequency clock pin. RHCKD must be set for
proper ESAI_1 receiver section operation.
11.3.5
ESAI_1 RECEIVE CONTROL REGISTER (RCR_1)
The read/write Receive Control Register (RCR_1) controls the ESAI_1 receiver section.
Hardware and software reset clear all the bits in the RCR_1 register.
