Preliminary specification
P87C51MB2/P87C51MC2
80C51 8-bit microcontroller family with extended memory
64KB/96KB OTP with 2KB/3KB RAM
UARTS
P87C51Mx2 includes two enhanced UART ports with one independent Baud Rate Generator:
UART 0 is the standard 51MX enhanced UART as described in the User Manual. It can be selected to use Timer1 overflow,
Timer2 overflow or the independent Baud Rate Generator.
UART 1 only uses the independent Baud Rate Generator to generate its baud rate. It has the same baud rate for both
transmission and reception.
The Baud Rate Generator is described in the User Manual.
Each of the UARTs has one set of enhanced UART SFRs. Please refer to the descriptions on the corresponding SFRs in the
User Manual:
PCON.7 and PCON.6 SFR Bits
The PCON.7 and PCON.6 SFR bits configure the UARTs as follows:
PCON.7 (SMOD1) - Baud Rate Control bit for serial port 0. When 0, the baud rate for UART 0 will be the input rate (T1 timer
or baud rate generator, as determined by the BRGCON extended SFR) divided by two. When 1, the baud rate for UART 0 will
be the input rate (T1 timer or baud rate generator). UART 1 is not affected by this bit
PCON.6 (SMOD0) - Framing Error Location:
- When 0, bit 7 of S0CON and S1CON will function as SM0 for UARTs 0 and 1 respectively.
- When 1, bit 7 of S0CON and S1CON will be used for framing error status for UART 0 and 1 respectively.
PCON.6 also determines when the UART receive interrupts RI_0 and RI_1 occur in UART modes 2 or 3. (Refer to User
Manual for details.)
