• Description: 64/100-pin General Purpose, 32-bit Flash Microcontrollers
• Manufacturer: Microchip Technology Inc.

EXAMPLE 17-4:
17.4
Enabling the SPI modules will configure the I/O pin
direction as defined by the SPI control bits (see
Table 17-7). The port TRIS and LATCH registers will be
overridden.

Note:
The following code example demonstrates a simple interrupt service routine for SPI1
interrupts. The user’s code at this vector should perform any application specific operations
and must clear the SPI1 interrupt flags before exiting.
// ... perform application specific operations in response to the interrupt
IFS0CLR = 0x03800000;
I/O Pin Control
The SPI1 ISR code example shows MPLAB
Refer to your compiler manual regarding support for ISRs.
