11.3.2.15 USART2 RECEIVE INTERRUPT
There are two ways to enable the USART2 Receive Interrupt:
Library Call
To enable the USART2 Receive Interrupt through a library call, you must include the
usart16.h
also allows you to configure the USART2. For more information on how to configure
the USART2, refer to the MPLAB C17 C Compiler Libraries (DS51296). The following
code snippet only shows how to go about enabling the USART2 Receive Interrupt.
Modifying Register Bits
This section only discusses the bits necessary to enable the USART2 Receive
Interrupt. For information on configuring the USART2, please refer to the section in
the PIC17C7XX Data Sheet on the Receive Status and Control Register (RCSTA2).
To enable the USART2 receive interrupt, you must clear the following bit flags:
• The Peripheral Interrupt Request Register2’s (PIR2’s) USART2 Receive Interrupt
• The INTSTA register’s Peripheral Interrupt Flag (PEIF) bit – [INTSTA<7>]. This
11.3.2.16 SYNCHRONOUS SERIAL PORT INTERRUPT
To enable the Synchronous Serial Port Interrupt, you must clear the following bit flags:
• The Peripheral Interrupt Request Register2’s (PIR2’s) Synchronous Serial Port
• The INTSTA register’s Peripheral Interrupt Flag (PEIF) bit – [INTSTA<7>]. This
Note: PIC17C7XX devices only.

Flag (RC2IF) bit – [PIR2<0>].
clears any previous occurrences of USART2 receive interrupts. In addition, you
must set the following enable bits:
- The Peripheral Interrupt Enable Register2’s (PIE2’s) USART2 Receive Inter-
- The INTSTA register’s Peripheral Interrupt Enable (PEIE) bit – [INTSTA<3>].
Note: PIC17C7XX devices only.
Interrupt Flag (SSPIF) bit – [PIR2<7>].
clears any previous occurrences of synchronous serial port interrupts. In addition,
you must set the following enable bits:
- The Peripheral Interrupt Enable Register2’s (PIE2’s) Synchronous Serial Port
- The INTSTA register’s Peripheral Interrupt Enable (PEIE) bit – [INTSTA<3>].
- PIR2bits.SSPIF = 0;
- PIE2bits.SSPIE = 1;
- INTSTAbits.PEIF = 0;
- INTSTAbits.PEIE = 1;
