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 CT
3
bit is set to 0) and the level mode (when the CT
3
bit is set
to 1). The CTFG bit can be set only when the CT
3
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.
