PIC17C7XX DEVICES
To enable the TMR1 overflow interrupt for PIC17C7XX devices, you must clear the
following bit flags:
• The Peripheral Interrupt Request Register1’s (PIR1’s) TMR1 Interrupt Flag
• The Timer1 On (TMR1ON) bit – [TCON2<0>]. This stops the timer until you are
• The INTSTA register’s Peripheral Interrupt Flag (PEIF) bit – [INTSTA<7>]. This
PIC17C4X DEVICES
To enable the TMR1 overflow interrupt for PIC17C4X devices, you must clear the
following bit flags:
• The Peripheral Interrupt Request Register’s (PIR) TMR1 Interrupt Flag (TMR1IF)
• The Timer1 On (TMR1ON) bit – [TCON2<0>]. This stops the timer until you are
• The INTSTA register’s Peripheral Interrupt Flag (PEIF) bit – [INTSTA<7>]. This
(TMR1IF) bit – [PIR1<4>].
ready to use it. See below for how to start the timer.
clears any previous occurrences of TMR1 overflow interrupts. In addition, you
must set the following enable bits:
- The Peripheral Interrupt Enable Register1’s (PIE1’s) TMR1 Interrupt Enable
- The INTSTA register’s Peripheral Interrupt Enable (PEIE) bit – [INTSTA<3>].
bit – [PIR<4>].
