Bit Definitions:
SPUA if set to 1, the strong pullup to 5V is currently active, if
set to 0, it is inactive.
PRGA if set to 1, a 12V programming pulse is currently being
generated, if set to 0, it is not.
12VP if set to 1, the external 12V programming voltage is
present, if set to 0, it is not present.
PMOD if set to 1, the DS2490 is powered from USB and
external sources, if set to 0, all DS2490 power is
provided from USB.
HALT if set to 1, the DS2490 is currently halted, if set to 0, the
device is not halted.
IDLE if set to 1, the DS2490 is currently idle, if set to 0, the
device is not idle.
bit 6: Reserved

Communication command currently being processed. If the device
is idle, a register value of 0x00 is sent.
Communication
Command, Byte 2
0x0A
Communication command currently being processed. If the device
is idle, a register value of 0x00 is sent.
Communication
Command Buffer Status
0x0B
Number of data bytes currently contained in the 16-byte FIFO used
to hold communication commands.
1-Wire Data Out Buffer
Status
0x0C
Number of data bytes currently contained in the 128-byte FIFO
used to write data to the 1-Wire bus.
1-Wire Data In Buffer
Status
0x0D
Number of data bytes currently contained in the 128-byte command
FIFO used to read data from the 1-Wire bus.

Notes:
1. If EP0F is set to 1, the Endpoint 0 FIFO was full when a new control transfer setup packet was
received. This is an error condition in that the setup packet received is discarded due to the full
