Serial Port Mode 2:
Mode 3
This mode is similar to Mode 2 in all respects; expect that the baud rate is programmable. The user must first initialize
the Serial related SFR SCON before any communication can take place. This involves selection of the Mode and
Baud rate. The Timer 1 should also be initialized if modes 1 and 3 are used. In all four modes, transmission is started
by any instruction that uses SBUF as a destination register. Reception is initiated in Mode 0 by the condition RI = 0
and REN = 0. This will generate a clock on the TxD pin and shift in 8 bits on the RxD pin. Reception is initiated in
the other modes by the incoming start bit if REN = 1. The external device will start the communication by
transmitting the start bit.
Pulse Width Modulation (PWM)
The PWM output pins are P1.4 and P1.5.
The PWM clock is {Fosc/ (2xDivider)}, the PWM output frequency is {(PWM clock)/32} at 5 bits resolution and
{(PWM clock)/256} at 8 bits resolution.
The PWM SFR is shown as below:
