MB91101/MB91101A
3. UART
The UART is a serial I/O port for supporting asynchronous (start-stop system) communication or CLK synchro-
nous communication, and it has the following features.
The MB91101 and MB91101A consist of 3 channels of UART.
⢠Full double double buffer
⢠Both a synchronous (start-stop system) communication and CLK synchronous communication are available.
⢠Supporting multi-processor mode
⢠Perfect programmable baud rate
Any baud rate can be set by internal timer (refer to section â4. U-TIMERâ).
⢠Any baud rate can be set by external clock.
⢠Error checking function (parity, framing and overrun)
⢠Transfer signal: NRZ code
⢠Enable DMA transfer/start by interrupt.
