PERIPHERAL INTERRUPT REGISTER 2 (PIR2: 0Dh)
bit 7
LVDIF: Low Voltage Detect Interrupt Flag bit
1 = The supply voltage has fallen below the specified LVD voltage (must be cleared in software)
0 = The supply voltage is greater than the specified LVD voltage
Unimplemented: Read as '0'
BCLIF: Bus Collision Interrupt Flag bit
1 = A bus collision has occurred while the SSP module configured in I
0 = No bus collision occurred
Unimplemented: Read as '0'

Interrupt flag bits get set when an interrupt
condition occurs, regardless of the state of
its corresponding enable bit or the global
enable bit, GIE (INTCON<7>). User soft-
ware should ensure the appropriate inter-
rupt flag bits are clear prior to enabling an
interrupt.
