PIC12F629/675
5.0
The PIC12F629/675 devices have a 16-bit timer.
Figure 5-1 shows the basic block diagram of the Timer1
module. Timer1 has the following features:
• 16-bit timer/counter (TMR1H:TMR1L)
• Readable and writable
• Internal or external clock selection
• Synchronous or asynchronous operation
• Interrupt on overflow from FFFFh to 0000h
• Wake-up upon overflow (Asynchronous mode)
• Optional external enable input (T1G)
• Optional LP oscillator
