The IEP digital I/O supports the following features:
The industrial digital I/Os supported by the PRU-ICSS IEP peripheral are described in Table 7-92.
Direction | Port | Mapped to Device I/Os | Notes |
---|---|---|---|
output | PR<k>_IEP0_EDIO_DATA_IN_OUT[0:31] | PR0_IEP0_EDIO_DATA_IN_OUT[31:28] |
Only PR<k>_IEP0_EDIO_DATA_IN_OUT[31:28] are exported to device pins as a bidirectional. |
