7.3.1 Interrupt Data Transfer Types Supported
The IOCTL_ENABLE_IRQEVENT IOCTL call is used to enable an IRQ event. It allows the user to
configure the data to fetch during the interrupt service routine. The following data types are
supported:
 ISR_NODATA — reads zeroes
 ISR_READ_16COUNT — reads a timer counter channel
 ISR_READ_16COUNTSTAT — reads a TC channel's status and count (Version 4.40 onwards)
 ISR_READ_32COUNT — reads two chained counters
 ISR_READ_32COUNTSTAT — reads two TC channels' status and counts (Version 4.40 onwards)
 ISR_READ_PPIABC — reads data from all 3 PPI ports
 ISR_READ_PPIC — reads data from PPI port C (Version 2.00 onwards)
 ISR_PC27 — reads PC27 ADC port (Version 2.01 onwards)
 ISR_READ_DATA8 — reads data from 1 DIO port (Version 3.00 onwards)
 ISR_READ_DATA16 — reads data from 2 DIO ports (Version 3.00 onwards)
 ISR_READ_ADCS — reads ADC channels (Version 4.00 onwards)
 ISR_READ_ADCSNOFIFO — reads ADC channels (Version 4.02 onwards)
 ISR_READ_ADCSFIFO — reads ADC channels (Version 4.10 onwards)
 ISR_READ_ADCSASAP — reads ADC channels (Version 4.40 onwards)
 ISR_READ_2PPIABC — reads data from 6 PPI ports on 2 PPI chips (Version 4.35 onwards)
 ISR_READ_3PPIABC — reads data from 9 PPI ports on 3 PPI chips (Version 4.35 onwards)
 ISR_WRITE_DATA8 — writes data to 1 DIO port (Version 3.00 onwards)
