Address: 0x8003_0058
Default: 0x0000_0000
Definition: Parallel Interface Output/Control Register.
This register, if PIFEN = ‘1’ in the VideoAttribs register, is used to access a
Smart Panel. A Smart Panel has an integrated controller and frame buffer.
Bit Descriptions:
RSVD:
Reserved - Unknown during read
RD:
Read control bit - Write Only
Writing a ‘0’ to this bit location will initiate a parallel
interface write cycle; writing a ‘1’ will initiate a parallel
interface read cycle:
1 - Start Smart Panel write cycle
0 - Start Smart Panel read cycle
DAT:
Data - Write Only
The value written to this field is output on the parallel
interface pins during a write cycle. Writing PIFEN = ‘1’ to
the VideoAttribs register redefines the signals on these
pins for Parallel Interface (Smart Panel) operation:
V_CSYNC --> D7 (Smart Panel)
HSYNC --> D6
BLANK --> D5
P17 --> D4
