9.3.2.1 TCCR_1 Tx High Freq. Clock Divider (TFP3-TFP0) - Bits 14–17
Since the ESAI_1 does not have the transmitter high frequency clock pin, the TFP3–TFP0 bits simply
specify an additional division ratio in the clock divider chain. See
Figure 9-4 .
9.3.2.2 TCCR_1 Tx High Freq. Clock Polarity (THCKP) - Bit 20
The ESAI_1 does not have the transmitter high frequency clock pin. It it recommended that THCKP
should be kept cleared.
9.3.2.3 TCCR_1 Tx High Freq. Clock Direction (THCKD) - Bit 23
The ESAI_1 does not have the transmitter high frequency clock pin. THCKD must be set for proper
ESAI_1 transmitter section operation.
