Receiver Clock Management
The transmitter can also drive the TX_CLOCK I/O pad continuously or be limited to the actual
data transfer. The clock output is configured by the TCMR register. The Transmit Clock Inver-
sion (CKI) bits have no effect on the clock outputs. Programming the TCMR register to select
TX_CLOCK pin (CKS field) and at the same time Continuous Transmit Clock (CKO field) might
lead to unpredictable results.
Figure 25-6. Transmitter Clock Management
The receiver clock is generated from the transmitter clock or the divider clock or an external
clock scanned on the RX_CLOCK I/O pad. The Receive Clock is selected by the CKS field in
RCMR (Receive Clock Mode Register). Receive Clocks can be inverted independently by the
CKI bits in RCMR.
The receiver can also drive the RX_CLOCK I/O pad continuously or be limited to the actual data
transfer. The clock output is configured by the RCMR register. The Receive Clock Inversion
(CKI) bits have no effect on the clock outputs. Programming the RCMR register to select
RX_CLOCK pin (CKS field) and at the same time Continuous Receive Clock (CKO field) can
lead to unpredictable results.
