STMPE811
Interrupt system
23/54
INT_EN
Interrupt enable register
Address:
0x0A
Type:
R/W
Reset:
0x00
Description:
The interrupt enable register is used to enable the interruption from a system related
interrupt source to the host.
INT_STA
Interrupt status register
Address:
0x0B
Type:
R
Reset:
0x10
Description:
The interrupt status register monitors the status of the interruption from a particular
interrupt source to the host. Regardless of whether the INT_EN bits are enabled, the
INT_STA bits are still updated. Writing '1' to this register clears the corresponding
bits. Writing '0' has no effect.
