Microcontrollers for monitors with DDC
interface, auto-sync detection and sync proc.
P83Cx80; P87C380
3.
Indirect-addressable via MOVX-Datapointer or
MOVX-Ri instructions.
7.2.1
RAM
Four register banks, each 8 registers wide, occupy
locations 0 through 31 in the lower RAM area. Only one of
these banks may be enabled at a time. The next 16 bytes,
locations 32 through 47, contain 128 directly addressable
bit locations. The stack can be located anywhere in the
internal 256 bytes RAM. The stack depth is only limited by
the available internal RAM space of 256 bytes (see Fig.4).

(SFR

)
The SFRs can only be addressed directly in the address
range from 128 to 255 (see Fig.3). Figure 5 gives an
overview of the Special Function Registers space. Sixteen
address in the SFRs space are both byte and
bit-addressable. The bit-addressable SFRs are those
whose address ends in 0H and FH. The bit addresses in
this area are 80H to FFH
7.2.3
AUX-RAM
AUX-RAM buffer 0 to 255 is indirectly addressable as
external data memory locations 0 to 255 via
MOVX-Datapointer instruction or via MOVX-Ri instruction.
Since the external access function is not available, any
access to AUX-RAM 0 to 255 will not affect the ports.
The 256 bytes of AUX-RAM buffer used to support DDC
interface is also available for system usage by indirect
addressing through the address pointer DDCADR and
data I/O buffer RAMBUF. The address pointer (DDCADR)
is equipped with the post increment capability to facilitate
the transfer of data in bulk (for details refer to Chapter 17).
However, it is also possible to address the AUX-RAM
buffer through MOVX command as usually used in the
internal RAM extension of 80C51 derivatives.
