(TS8xC51Rx2) High Performance 8-bit Microcontroller

Atmel Corporation 

TS8xC51Rx2

It is possible to use timer 2 as a baud rate generator and a clock generator simulta-

neously. For this configuration, the baud rates and clock frequencies are not

independent since both functions use the values in the RCAP2H and RCAP2L registers.
