INT Function and Mask Options (09H: D3-D1)
Changes of the 08H status can be monitored via the INT pin. The INT pin is the open drain output and goes “L” for 2
μ
s
(typ.) when the status of 08H is changed. This pin should be connected to VD (typ. 5V) through 10k
resistor.
MVC bit, MTV bit, MFVCR bit and MSVCR bit control the reflection of the status change of these monitors onto the INT
pin from report to prevent to masks each monitor.

MSVCR: SVCR1-0 Monitor mask
0: Change of SVCR1-0 is reflected to INT pin. (Default)
1: Change of SVCR1-0 is NOT reflected to INT pin.
