3-wire serial I/O (CSI00, CSI01, CSI10, CSI11) performs the following six types of communication operations.
• Master transmission (See 15.5.1 Master transmission.)
• Master reception (See 15.5.2 Master reception.)
• Master transmission/reception (See 15.5.3 Master transmission/reception.)
• Slave transmission (See 15.5.4 Slave transmission.)
• Slave reception (See 15.5.5 Slave reception.)
• Slave transmission/reception (See 15.5.6 Slave transmission/reception.)
