Register SET_EP_ENABLE (address: 0xD8H)
Detailed description of the write (1 byte) following command 0xD8H
Table 52
Register GETSET_MODE (address: 0xF3H)
Detailed description of the write (one byte) following command 0xF3H; notes 1, 2 and 3
Notes
1.
2.
GETSET_MODE command can write from 1 to 4 consecutive bytes. The detailed description above concerns byte 0.
GETSET_MODE bytes 1 and 2 are used to set the size of the isochronous video packets. Byte 1 corresponds to the
LSB to define the packet size. Bits 0 and 1 of byte 2 set the 2 MSBs. By default, the two bytes are forced to 0.
GETSET_MODE byte 3 sets the FIFO offset.

FIFO_ACTIVE: set the video FIFO status
FIFO is inactive; only zero-length packet are sent upstream
functional mode (by default)
ALWAYS_PLLCLOCK: control internal clock signals
clocks and PLL are stopped whenever not needed (e.g. suspend mode)
clocks and PLL are always running even in suspend mode (by default)
INTERRUPT_ONNAK: control transaction reporting
only successful transactions are reported
NAK is reported and generates an interrupt (by default)
