mm are two hexadecimal values.
Each value is interpreted as 4 bits.
The first 4-bit value represents the status of channels 7-4, the second
4 bits represents the status of channels 3-0.
A value of 0 means the channel is disabled, while a value of 1 means
the channel is enabled.

Example The command asks the specific module at address 01h to send
Enable/Disable status of all analog input channels. The analog input
module responds that all its channels are enabled (FF equals 1111 and
1111).
