0 = No effect.
1 = Equivalent to a system reset.
0 = No effect.
1 = The slave mode is disabled. The shifter and holding characters (if it contains data) are transmitted in case of read operation.
In write operation, the character being transferred must be completely received before disabling.
0 = No effect.
1 = If SVDIS = 0, the slave mode is enabled.
Switching from Master to Slave mode is only permitted when TXCOMP = 1.
0 = No effect.
1 = The master mode is disabled, all pending data is transmitted. The shifter and holding characters (if it contains data) are
transmitted in case of write operation. In read operation, the character being transferred must be completely received before
disabling.
0 = No effect.
1 = If MSDIS = 0, the master mode is enabled.
Switching from Slave to Master mode is only permitted when TXCOMP = 1.
0 = No effect.
1 = STOP Condition is sent just after completing the current byte transmission in master read mode.
0 = No effect.
1 = A frame beginning with a START bit is transmitted according to the features defined in the mode register.
- In single data byte master read, the START and STOP must both be set.
- In multiple data bytes master read, the STOP must be set after the last data received but one.
- In master read mode, if a NACK bit is received, the STOP is automatically performed.
- In multiple data write operation, when both THR and shift register are empty, a STOP condition is automatically sent.
