• Start bit: 1 bit long
• Parity bit: selectable among odd, even, or none
• Stop bit: selectable from 1 bit or 2 bits long
• The CKDIR bit in the G1MR register is set to 0 (internal clock)
• Bits CCS3 and CCS2 in the CCS register is set to 00b (Clock generated with waveform
The internal transmit clock is generated in phase-delayed waveform output mode of the channel 3.
The internal receive clock is generated by performing both the time measurement and phase-
delayed waveform output in the channel 2.
Set registers associated with the waveform generation function and the G1MR register. Then
wait for one or more internal transmit clock cycles before all of the following conditions are met to
start the transmit operation.
Set registers associated with the waveform generation function and the G1MR register. Then
wait for one or more internal receive clock cycles before all of the following conditions are met to
start the receive operation.
Transmit interrupt (The IRS bit in the G1MR register selects one of the following):
Receive interrupt:
• Overrun error
• Framing error
• Parity error
Each error flag is updated when the data is transferred from the receive shift register to the G1RB
register every time a receive operation is completed.
• LSB first or MSB first
• Data length: 8 bits long
The SIO1TR bit in the IIO3IR register becomes 1 (interrupt requested) when a transmit interrupt
request is generated (Refer to Figure 11.18).
The SIO1RR bit in the IIO2IR register becomes 1 (interrupt requested) when a receive interrupt
request is generated (Refer to Figure 11.18).

•The TE bit in the G1CR register is set to 1 (transmit operation enabled)
•The TI bit in the G1CR register is 0 (data in the G1TB register)
•The RE bit in the G1CR register is set to 1 (receive operation enabled)
•Detecting the start bit (“L” level)
•When the IRS bit is set to 0 (no data in the GiTB register):
•When the IRS bit is set to 1 (transmit operation completed):
•When data is transferred from the receive shift register to the G1RB register (receive operation
Overrun error occurs when the preceding bit of the final stop bit of the next data (the first stop
bit when selecting 2 stop bits) is received before reading the G1RB register. If an overrun error
occurs, a read from the G1RB register returns an undefined value.
Framing error occurs when the number of the stop bits set by the STPS bit in the G1MR register
is not detected.
Parity error occurs when parity is enabled and the received data does not have the correct even
or odd parity set by the PRY bit in the G1MR register.
Data is transmitted or received from either bit 0 or bit 7.
