(aadd) $1B $77
[Name]
Write data (dd) in address (aa)
[Format] ASCII aH aL dH dL ESC w
Hex aH aL dH dL 1B 77
Decimal aH aL dH dL 27 119
[Range]
[Description]
Save datad in addressa in the memory (EEPROM):
aH is the most signi fi cant nibble of a expressed in ASCII
aL is the least signi fi cant nibble of a expressed in ASCII
dH is the most signi fi cant nibble of d expressed in ASCII
dL is the least signi fi cant nibble ofd expressed in ASCII
[Notes] • There are 256 writable locations (from $00 to $FF); the data maximum is $FF (255) and
both the addresses and the data must be expressed in ASCII on two bytes
[Default] The whole memory bank contains the value $20 by default
[Reference] $1B $72
[Example] To save the data $A5 in the address $01, transmit:
$30 $31 $41 $35 $1B $77
(dd) $1B $47
[Name]
Write the value (dd) in the option register
[Format] ASCII dH dL ESC G

[Range]
[Description]
Modify the con fi guration register.
(dd) are two ascii characters which represent the hexadecimal code for the programming of
the register; in the following table is indicated the value of dd send it in a byte format:
