2.1-6 (CTFG)
The CTFG bit is set to 1 when interrupt pulses are output from the INTR pin held at the low level. There are two
interrupt modes selectable: the pulse mode (when the CT3 bit is set to 0) and the level mode (when the CT3 bit is set
to 1). The CTFG bit can be set only when the CT3 is set to 1. Setting the CTFG bit to 1 switches the INTR pin to the
low level while setting the CTFG bit to 0 turns off the INTR pin.
