Special Function Register for the DDC Interface
There are eight SFR in the DDC interface:
RAMBUF, DDCCON, DDCADR, DDCDAT are
DDC registers.
S1CON, S1STA, S1DAT, S1ADR are I
2
C Inter-
face registers, same as the ones described in the
standalone I
2
C bus.
DDCDAT Register.
DDC1 DATA register for
transmission (DDCDAT: 0D5H)
I
8-bit READ and WRITE register.
I
Indicates DATA BYTE to be transmitted in
DDC1 protocol.
DDCADR Register.
Address pointer for DDC in-
terface (DDCADR: 0D6H)
I
8-bit READ and WRITE register.
I
Address pointer with the capability of the post
increment. After each access to RAMBUF
register (either by software or by hardware
DDC1 interface), the content of this register will
be increased by one. It’s available both in
DDC1, DDC2 (DDC2B, DDC2B+, and
DDC2AB) and system operation.
