27 / 58 page  STMPE1601 Interrupt system 27/58 INT_EN_GPIO_MASK Interrupt enable GPIO mask register Address: 0x16, 0x17 Type: R/W Buffer: Reset: 0x00 Description: The interrupt enable GPIO mask register is used to enable the interruption from a particular GPIO interrupt source to the host. The IEG[15:0] bits are the interrupt enable mask bits correspond to the GPIO[15:0] pins . INT_STA_GPIO Interrupt status GPIO register Address: 0x18, 0x19 Type: R/W Buffer: Reset: 0x00 Description: The interrupt status GPIO register monitors the status of the interruption from a particular GPIO pin interrupt source to the host. Regardless whether the INT_EN_GPIO_MASK bits are enabled or not, the INT_STA_GPIO bits are still updated. The INT_STA_G[15:0] bits are the interrupt status bits correspond to the GPIO[15:0] pins. 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 INT_EN_GPIO_MASK_msb INT_EN_GPIO_MASK _lsb IEG15 IEG14 IEG13 IEG12 IEG11 IEG10 IEG9 IEG8 IEG7 IEG6 IEG5 IEG4 IEG3 IEG2 IEG1 IEG0 RW RW RW RW RW RW RW RW RW RW RW RW RW RW RW RW 00 0000 0 0 0 0 0 0 0 0 0 0 [15:0] IEG[x]: interrupt enable GPIO mask (where x = 15 to 0) Writing a ‘1’ to the IE[x] bit will enable the interruption to the host. 15 14 13 12 11 10 9876543210 INT_STA_GPIOR_msb INT_STA_GPIOR _lsb ISG15 ISG14 ISG13 ISG12 ISG11 ISG10 ISG9 ISG8 ISG7 ISG6 ISG5 ISG4 ISG3 ISG2 ISG1 ISG0 RW RW RW RW RW RW RW RW RW RW RW RW RW RW RW RW 0 0 0 0 0 0 0000000000 [15:0] ISG[x] Interrupt status GPIO (where x = 15 to 0) Read: Interrupt status of the GPIO[x]. Write: A write to a ISG[x] bit with a value of ‘1’ will clear the interrupt and a write with a value of ‘0’ has no effect on the ISG[x] bit. |
