#147979 - if you'd just need one UART switchable between... Responding to: ???'s previous message |
... these two baudrates, a "classical" '51 with 24MHz crystal would do (the absolute perfect frequency would be 23.9616, but the difference is 0.16% which is negligible).
For 9600 baud, you'd use "divider" 13, for 10400 baud 12; in both cases SMOD=PCON.7=1. JW |
