Expression 3 - ETC

Channel data type
Channels normally contain 8-bit data but may be enabled to contain 16-bit
data. Enabling for 16-bit data always involves the next channel in order as
well. The enabled channel is called the “HI” channel because it holds the
high-order bits of the 16-bit data. The subsequent channel is called the
“LO” channel because it holds the low-order bits. Either may be
reassigned to 8-bit data, but when you do that, both channels of a 16-bit
pair are reassigned at once. Use the procedure below to enable one
channel or a range of channels for 16-bit data.
