C Bus Mode Data Formats
The following registers control the serial bus interface and provide its status information for
monitoring.
Serial bus interface control register 0 (SBI0CR0)
Serial bus interface control register 1 (SBI0CR1)
Serial bus interface control register 2 (SBI0CR2)
Serial bus interface buffer register (SBI0DBR)
I
Serial bus interface status register (SBI0SR)
Serial bus interface baud rate register 0 (SBI0BR0)
The functions of these registers vary, depending on the mode in which the SBI is operating. For
a detailed description of the registers, refer to "15.5 Control in the I
Control in the Clock-synchronous 8-bit SIO Mode."
