SN8F2280 Series  
USB 2.0 Full-Speed 8-Bit Micro-Controller  
10 Universal Asynchronous  
Receiver/Transmitter (UART)  
10.1 OVERVIEW  
The UART interface is an universal asynchronous receiver/transmitter method. The serial interface is applied to low  
speed data transfer and communicate with low speed peripheral devices. The UART transceiver of Sonix 8-bit MCU  
allows RS232 standard and supports one and two bytes data length. The transfer format has start bit, 8/16-bit data,  
parity bit and stop bit. Programmable baud rate supports different speed peripheral devices. UART I/O pins support  
push-pull and open-drain structures controlled by register.  
The UART features include the following:  
z

Full-duplex, 2-wire asynchronous data transfer.  
Programmable baud rate.  
8-bit and 16-bit data length.  
Odd and even parity bit.  
End-of-Transfer interrupt.  
10.2 UART OPERATION  
The UART RX and TX pins are shared with GPIO. When UART enables (URXEN=1, UTXEN=1), the UART shared  
pins transfers to UART purpose and disable GPIO function automatically. When UART disables, the UART pins returns  
to GPIO last status. The UART data buffer length supports 1-byte and 2-byte. After UART RX operation finished, the  
UTRXIRQ sets as “1”. After UART TX operation finished, the UTTXIRQ sets as “1”. The UART IRQ bits are cleared by  
program. If the UTRXIEN or UTTXIEN set to enable, the UTRXIRQ and UTTXIRQ triggers the interrupt request and  
program counter jumps to interrupt vector to execute interrupt service routine.
