30.4.1 Synchronous Host Mode
The following bits are used to configure the EUSART for synchronous host operation:
- The SYNC bit is set to ‘
1
’ to configure the EUSART for synchronous operation - The Clock Source Select (CSRC) bit is set to ‘
1
’ to configure the EUSART as the host - The Single Receive Enable (SREN) bit is set to ‘
0
’ for transmit; SREN =1
for receive (recommended setting to receive 1 byte) - The Continuous Receive Enable (CREN) bit is set to ‘
0
’ for transmit; CREN =1
to receive continuously - The SPEN bit is set to ‘
1
’ to enable the EUSART interface
Important: Clearing the SREN and
CREN bits ensure that the device is in the Transmit mode, otherwise the device will be
configured to receive.
