Timer 1 Timer versatile 8-bit timer. Its main function is to operate as a Pulse Width Modulation (PWM) generator that generates pulses of a specified width and duty cycles. Timer 1 contains an 8-bit timer register ...

Page 20

Pulse Width Modulation (PWM) Mode In the PWM mode, the timer counts down at the instruction clock rate. When an underflow occurs, the timer register is reloaded from T1RA and the count down proceeds from the loaded value. At ...

Multi-Input Wakeup/Interrupt Block The Multi-Input Wakeup (MIW)/Interrupt contains three memory-mapped registers associated with this circuit: WKEDG (Wakeup Edge), WKEN (Wakeup Enable), and WKPND (Wakeup Pending). Each register has three bits with each bit corresponding to an input pins as ...

Page 23

I/O Port The six I/O pins are bi-directional with the exception of G3 which is always an input with weak pull-up (see Figure 19). The bi- directional I/O pins can be individually configured by software to operate as high-impedance ...
