UP
Except for the baud rate generator mode, the values given for T2CON do not include the setting of the TR2 bit. Therefore,
bit TR2 must be set, separately, to turn the timer on.

Capture/reload occurs only on timer/counter overflow.
Capture/reload on timer/counter overflow and a HIGH to LOW transition on T2EX, except when timer 2 is used in the
baud rate generator mode.

Capture/reload occurs only on timer/counter overflow.
Capture/reload on timer/counter overflow and a HIGH to LOW transition on T2EX (P1.1) pin except when timer 2 is
used in the baud rate generator mode.

Enhanced UART
The UART operates in all of the usual modes that are described in the first section of “Data Handbook IC20,
80C51-based 8-bit microcontrollers” In addition the UART can perform framing error detection by looking for missing
stop bits and automatic address recognition. The UART also fully supports multiprocessor communication as does the
standard 80C51 UART.
When used for framing error detection the UART looks for missing stop bits in the communication. A missing bit will set
the bit FE or bit 7 in the SCON register. Bit FE is shared with bit SM0. The function of SCON bit 7 is determined by bit 6
in register PCON (bit SMOD0). If SMOD0 is set then bit 7 of register SCON functions as FE and as SM0 when SMOD0
is cleared. When used as FE this bit can only be cleared by software.
