In clock synchronous serial I/O mode, data is transmitted and received using a transfer clock.
Table 23.2 lists the Clock Synchronous Serial I/O Mode Specifications. Table 23.3 lists the Registers Used and
Settings in Clock Synchronous Serial I/O Mode
1. When an external clock is selected, the requirements must be met in either of the following states:
2. If an overrun error occurs, the receive data (b0 to b8) in the UiRB register will be undefined.
- The external clock is held high when the CKPOL bit in the UiC0 register is set to 0 (transmit data
- The external clock is held low when the CKPOL bit in the UiC0 register is set to 1 (transmit data
The IR bit in the SiRIC register remains unchanged.

Clock Synchronous Serial I/O Mode Specifications
Oct 30, 2009
• Transfer data length: 8 bits
• The CKDIR bit in the UiMR register is set to 0 (internal clock): fi/(2(n+1))
• The CKDIR bit is set to 1 (external clock): Input from the CLKi pin
• To start transmission, the following requirements must be met:
• To start reception, the following requirements must be met:
• For transmission, one of the following can be selected.
• For reception
• Overrun error
• CLK polarity selection
• LSB first, MSB first selection
• Continuous receive mode selection
fi = f1, f8, f32, fC n = Value set in UiBRG register: 00h to FFh
- The TE bit in the UiC1 register is set to 1 (transmission enabled).
- The TI bit in the UiC1 register is set to 0 (data in the UiTB register).
- The RE bit in the UiC1 register is set to 1 (reception enabled).
- The TE bit in the UiC1 register is set to 1 (transmission enabled).
- The TI bit in the UiC1 register is set to 0 (data in the UiTB register).
- The UiIRS bit is set to 0 (transmit buffer empty):
- The UiIRS bit is set to 1 (transmission completed):
When data is transferred from the UARTi receive register to the UiRB
register (at completion of reception).
This error occurs if the serial interface starts receiving the next unit of data
before reading the UiRB register and receives the 7th bit of the next unit of
data.
Transfer data input/output can be selected to occur synchronously with the
rising or the falling edge of the transfer clock.
Whether data transmission/reception begins with bit 0 or begins with bit 7
can be selected.
Reception is enabled immediately by reading the UiRB register.
When data is transferred from the UiTB register to the UARTi transmit
register (at start of transmission).
When data transmission from the UARTi transmit register is completed.
