Unimplemented: Read as '0'
EEIF: Data EEPROM/FLASH Write Operation Interrupt Flag bit
1 = The Write operation is complete (must be cleared in software)
0 = The Write operation is not complete, or has not been started
BCLIF: Bus Collision Interrupt Flag bit
1 = A bus collision occurred (must be cleared in software)
0 = No bus collision occurred
LVDIF: Low Voltage Detect Interrupt Flag bit
1 = A low voltage condition occurred (must be cleared in software)
0 = The device voltage is above the Low Voltage Detect trip point
TMR3IF: TMR3 Overflow Interrupt Flag bit
1 = TMR3 register overflowed (must be cleared in software)
0 = TMR3 register did not overflow
