THCV231_16 Datasheet, PDF (28/56 Pages) THine Electronics, Inc. – The THCV231 and THCV236 are designed to support video data transmission between the host and display.

Interruption
INT pin outputs interrupt event indicator on Sub-Link Master side of the system. The INT signal is active low.
Being set by 2-wire serial interface, the THCV231 and THCV236 can monitor any changes of GPIO input pins,
Sub-Link communication statuses and internal statuses as an interrupt. About the way to make interruption occur
and the way to clear the interruption, see Table 31(Address 0x02, 0x03) and Table 32(Address 0x82, 0x83).
