Interrupt controller module
STMPE821
20/55
INT_CTRL
Interrupt control register
Address:
0x08
Type:
R/W
Reset:
0x00
Description:
This register is used to enable control the polarity, edge/level and enabling of the
interrupt system.device
7
654
3210
POLARITY
TYPE
INT_EN
[7:3] RESERVED
[2] POLARITY:
'0' for active low
'1' for active high
For active low operation, the INT pin should be externally pulled high (up to 3.3 V, but
≤VIO).
The INT pin will be pulled to GND when there is a pending interrupt.
For active high operation, the INT pin should be externally pulled to GND. In this mode, the INT
pin will be pulled to VCC by the device when there is a pending interrupt.
[1] TYPE:
'0' for level trigger
'1' for edge trigger (pulse width is 200 nS)
[0] INT_EN:
'0' to disable all interrupt
'1' to enable all interrupt
