Data buffer
 Transmission data buffer/transmission data buffer for wait (exclusively for transmission; data
length of 1, 7, 8, and 9 bits supported)
 UART buffer (exclusively for transmission; variable data length from 1 to 9 bits; data length of 7
and 8 bits supported)
 Reception data buffer (exclusively for reception; data length of 1, 7, 8, and 9 bits supported)
Data format
 Character length: 7 or 8 bits
9 bits including the expansion bit supported.
 Transmission stop bit: 1 or 2 bits
 Parity function: odd, even, 0, or none
 LSB- or MSB-first transfer selectable
 Reverse input/output of transmission/reception data
Status
 Transmission status
 Reception status
 Successful UART buffer transmission
 Error SUM
 Expansion bit detection
 ID match
 Reset mode status
Error status
 Bit error
 Framing error
 Parity error
 Overrun error
Baud rate
selection
With the baud rate generator incorporated, any baud rate can be set.
If the expected level is detected for any expansion bit, the 8 bits of the received data can be compared to the preset
register data.
The stop bit received is guaranteed (start of transmission can be delayed when start of transmission is attempted
during reception of the stop bit).
Interrupt
function
 Transmission start/successful transmission
 Successful reception
 Status detection
Notes 1. Since the same register is used for setting, the inter-byte space (header) = response space.
2. For wake-up reception, the low level width of the input signal is indicated.
