Address:
EXTAD — DDC Expanded Address
D2AD[7:1] — DDC2 Address

Write:
This bit is set to expand the calling address of the DDC in slave mode.
When set, the DDC will acknowledge the general call address $00
and the matched 4-bit MSB address, DAD[7:4].
For example, when DAD[7:1] = $A1 and EXTAD = 1, the DDC calling
address is $A0, and it will acknowledge calling addresses $00 and
$A0 to $AF.
Reset clears this bit.
These 7 bits represent the second slave address for the DDC2BI
protocol. D2AD[7:1] should be set to the same value as DAD[7:1] in
DADR if user application do not use DDC2BI. Reset clears all bits this
register.
1 = DDC calling address is $DAD[7:4]0
0 = DDC address id $DAD[7:1]

$001C
Bit 7
DDC respond address is $00, and $DAD[7:4]0 to $DAD[7:4]F
