MB90220 Series
4. UART0
UART0 is a serial I/O port for synchronous or asynchronous communication with external resources. It has the
following features:
Full duplex double buffer
CLK synchronous and CLK asynchronous data transfers capable
Multiprocessor mode support (Mode 2)
Built-in dedicated baud-rate generator (12 rates)
Arbitrary baud-rate setting from external clock input or internal timer
Variable data length (7 to 9 bits (without parity bit); 6 to 8 bits (with parity bit))
Error detection function (Framing, overrun, parity)
Interrupt function (Two sources for transmission and reception)
Transfer in NRZ format
The MB90220 has three of these modules on chip.
