DS90UB948-Q1: interrupt questions of touch panel

Kailyn Chen

Hello，

Below is the application diagram.

Description: The interrupt pin of the touch panel connected INTB_IN of DS90UB948 and then output to UB941, two UB948 connected to UB941 as the above diagram.

Questions: Due to two Touch panels output to one UB941 through two UB948. At last I want REM_INTB and INTB of UB941 to identify which 948 pass the interrupt signal.

For example, REM_INTB output is TP1's interrupt ,INTB output is TP2's interrupt.

1. If REM_INTB_CTRL of UB941 need configure 0x01?

2.if the ICR register of UB941 also need configure, register 0xC6[5] = 1 and 0xC6[0] = 1 ?

3. the port1 and port 0 of REM_INTB is referred the external two 948? DOUT1-/DOUT1+ and DOUT0-/DOUT0+.

4. As the general application is 941->948->DISPLAY, while the TP interrupt is opposite. So the 948 and 941 could realize bi-directional transmission by LVDS?
