BCLIF: Bus Collision Interrupt Flag bit
1
= A bus collision occurred (must be cleared in software)
0
= No bus collision occurred
bit 2
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
bit 1
