Preliminary specification
P87C51MB2/P87C51MC2
80C51 8-bit microcontroller family with extended memory
64KB/96KB OTP with 2KB/3KB RAM
Baud Rate Selection
UART 0 and UART 1 selects the baud rate differently as shown in Tables 4 and 5:
S0CON.7
(SM0_0)
S0CON.6
(SM1_0)
T2CON.5/4
(RCLK - Receive
TCLK - Transmit)
PCON.7
(SMOD1)
BRGCON.1
(S0BRGS)
