Frequently Asked Question
What does the PULS field in the EDMOD registers do?
The ADV202/212 allows the DREQ/ pulse to be configured in two ways:
- DREQ/ is asserted until the host processor responds with a DACK/ assert. This requires the DRxPULS bits in the EDMODx register to be set to '0000'.
- DREQ/ pulse width is programmable and does not require a DACK/ for DREQ/ de-assertion. The pulse width is set with the DRxPULS bits in the EDMODx registers.
Refer to the datasheet for timing diagrams for both modes.
