Command: r <address> <register> <length>
<address> is the device address in hexadecimal format. For example, 30 for device address 0x30.
<register> is the register in hexadecimal format that will be read from.
<length> is the number of bytes that will be read from <register> in auto-increment mode.
The result will be displayed in the right-side output window of the command interpreter dialog.

<mask>
<address> is the device address in hexadecimal format. For example, 30 for device address 0x30.
<register> is the register in hexadecimal format that will be read from.
<mask> is a 8-bit binary format mask that is compared with the data from the device. Each bit can be
0, 1, or X.
For example: <mask> = 010XX01X tests, if the data from the device has D7 = 0, D6 = 1, D5 = 0, D4 =
don’t care, D3 = don’t care, D2 = 0, D1 = 1, D0 = don’t care.
[optional timeout] specifies how long (milliseconds) the command interpreter will poll the device if the
data do not match the <mask>
