Smart Panel R/W and RS signals must be implemented
via GPIOs and controlled via software.
Reserved - Unknown during read
Enable Start - Read/Write
The Enable Signal Start Value for the parallel interface
down counter should be written to this field. When the
parallel interface counter counts down to this value during
a write cycle (see RD bit in the
cycle), the E enable signal on the E pin goes active.
The E enable signal becomes inactive just before the
counter counts down to 0x0, although data remains driven
on the D[7:0] pins throughout the 0x0 count. This allows
data to be driven for one additional clock cycle, providing
data hold time to the Smart Panel.
Count - Read/Write
The counter preload value that is written to this field gets
loaded into the parallel interface down counter. When a
write or read cycle is initiated by writing to the RD bit in the
ParllIfOut
this value.
