SLDS171 – NOVEMBER 2009
UART Communication
Communication Protocol
Protocol: UART
Transfer Rate: See Table 21
Data transfer: See Table 21
Internal Oscillator : 38.4k x 16 x 4 = 2.458 MHz
Data length = 8 bit, Start bit = 1 bit, Stop bit = 1, Parity = even
Error detection: parity error, over run error, framing error. Ignore the frame when error is detected.
Time out for "packet not done" is 13 bit. Ignore received data. No response.
NU: IC to microprocessor is 0. microprocessor to IC 1 or 0.
Interval Rx-Rx = 2 bit to 13 bit, Rx-Tx = 1.5 bit, Tx-Tx = 2 bit
