Transmitter Operations
Serial Clock Ratio Considerations
Figure 25-7. Receiver Clock Management
The Transmitter and the Receiver can be programmed to operate with the clock signals provided
on either the TX_CLOCK or RX_CLOCK pins. This allows the SSC to support many slave-mode
data transfers. In this case, the maximum clock speed allowed on the RX_CLOCK pin is:
In addition, the maximum clock speed allowed on the TX_CLOCK pin is:
A transmitted frame is triggered by a start event and can be followed by synchronization data
before data transmission.
The start event is configured by setting the Transmit Clock Mode Register (TCMR).
“25.7.4” on page 267.
The frame synchronization is configured setting the Transmit Frame Mode Register (TFMR).
See Section “25.7.5” on page 269.
To transmit data, the transmitter uses a shift register clocked by the transmitter clock signal and
the start mode selected in the TCMR. Data is written by the application to the THR register then
transferred to the shift register according to the data format selected.
When both the THR and the transmit shift register are empty, the status flag TXEMPTY is set in
SR. When the Transmit Holding register is transferred in the Transmit shift register, the status
flag TXRDY is set in SR and additional data can be loaded in the holding register.
