AS7263 − Detailed Description

In the Figure below, numeric values may be specified with no

leading prefix, in which case they will be interpreted as

decimals, or with a leading “0x” to indicate that they are

hexadecimal numbers, or with a leading “‘b” to indicate that

they are binary numbers. The commands are loosely grouped

into functional areas. Texts appearing between angle brackets

(‘<‘ and ‘>‘) are commands or response arguments. A carriage

return character, a linefeed character, or both may terminate

commands and responses. Note that any command that

encounters an error will generate the “ERROR” response shown,

for example, in the NOP command at the top of the first table,

but has been omitted elsewhere in the interest of readability

and clarity.
