POWER MANAGEMENT SYSTEM DEVICE

10. INTC

INTC block detects the state change of external input signals (GPIO 14 bits) and the internal interrupt signals,

and then it generates interrupt signals. INTC block has the following functions; chattering rejection (30ms),

forward interrupt mask, backward interrupt mask, and interrupt detecting type selection (level/rising

edge/falling edge detection). The interrupt signal INTOUT, which is output from this block, continues to output

“H” until the interrupt factor registers (<FACTOR1~3>) are cleared. To Wakeup (Warm Boost) from Deep

Sleep/Suspend, INT_SIGNAL is used.
