13.3 Control Registers
The following registers are used to control CSIB0.
• CSIB0 control register 0 (CB0CTL0)
• CSIB0 control register 1 (CB0CTL1)
• CSIB0 control register 2 (CB0CTL2)
• CSIB0 status register (CB0STR)
(1) CSIB0 control register 0 (CB0CTL0)
CB0CTL0 is a register that controls the CSIB0 serial transfer operation.
This register can be read or written in 8-bit or 1-bit units.
Reset sets this register to 01H.
CB0CTL0
After reset: 01H
Note These bits can only be rewritten when the CB0PWR bit = 0.
Caution Be sure to clear bits 3 and 2 to “0”.
CB0PWR
CB0TXE
CB0RXE
CB0PWR
• The CB0PWR bit controls the CSIB0 operation and resets the internal circuit.
• The SOB0 output is low level when the CB0TXE bit is 0.
• When the CB0RXE bit is cleared to 0, no reception end interrupt is output even
CHAPTER 13 3-WIRE VARIABLE-LENGTH SERIAL I/O (CSIB)
when the prescribed data is transferred in order to disable the receive operation,
and the receive data (CB0RX register) is not updated.
