USB-MODEVM Protocol

www.ti.com

If the command is sent with no problem, the returning byte [0] is the same as the sent one logically ORed
with 0x20 - in the preceding first example, the returning packet is:

[0]

0x31

[1]

0xA0

[2]

0x02

[3]

0x05

[4]

0xAA

[5]

0x55

If for some reason the interface fails (for example, the I

C device does not acknowledge), it comes back

as:

[0]

0x51

--> interface | INTF_ERROR

[1]

0xA0

[2]

0x02

[3]

0x05

[4]

0xAA

[5]

0x55

If the request is malformed, that is, the interface byte (byte [0]) takes on a value which is not as preciously
described, the return packet is:

[0]

0x93

--> the user sent 0x13, which is not valid, so 0x93 returned

[1]

0xA0

[2]

0x02

[3]

0x05

[4]

0xAA

[5]

0x55

The preceding examples used writes. Reading is similar:
Read two bytes from device starting at register 5 of an I

C device with address A0:

[0]

0x01

[1]

0xA0

[2]

0x02

[3]

0x05

The return packet is:

[0]

0x21

[1]

0xA0

[2]

0x02

[3]

0x05

[4]

0xAA

[5]

0x55

assuming that the preceding values starting at Register 5 were actually written to the device.
