WebThe sbit keyword defines a bit within a register (SFR). It may be used like any of these three: sbit name = sfr-name ^ bit-position; sbit name = sfr-address ^ bit-position; sbit name = sbit-address; Here, our SFR (special function register) is P2 and the bit position is 0. So to set or clear a pin, we can now use: WebJan 25, 2024 · In the waveform generator, two switches are directly connected to the pins of the external interrupt 0 and the external interrupt 1, wherein the S1 switch is used to change the waveform and S2 switch to change the frequency. In the main function of the program, we write a dead loop that will always output a default waveform.
