13.2.7
Acknowledge Setup (F4H)
This command acknowledges to the host that a SETUP packet was received. The
arrival of a SETUP packet disables the Validate Buffer and Clear Buffer commands
for the control IN and OUT endpoints. The microcontroller needs to re-enable these
commands by sending an Acknowledge Setup command, see
Section 10.5
.
Code (hex): F4 —
acknowledge setup
Transaction —
none
13.3 DMA commands
13.3.1
DMA Function and Scratch register (R/W: B3H/B2H)
This command accesses the 16-bit DMA Function and Scratch register, which can be
used by the firmware to save and restore information. For example, the device status
before powering down in the suspend state. The register bit allocation is given in
Table 30
.
Code (hex): B2/B3 —
write or read DMA Function and Scratch register
Transaction —
write or read 2 bytes
3
OVERWRITE
This bit is set by hardware. Logic 1 indicates that a new Setup
packet has overwritten the previous setup information, before it
was acknowledged or before the endpoint was stalled. This bit is
cleared by reading, if writing the setup data has finished.
Firmware must check this bit before sending an Acknowledge
Setup command or stalling the endpoint. On reading logic 1, the
firmware must stop ongoing setup actions and wait for a new
Setup packet.
Logic 1 indicates that the buffer contains a Setup packet.
This bit indicates which buffer is currently selected for CPU
access (0 = primary buffer, 1 = secondary buffer).
