Smart Panel R/W and RS signals must be implemented
via GPIOs and controlled via software. The difference
between the CNT[3:0] value and the ESTRT[3:0] value is
what guarantees set up time for these GPIO signals to the
Smart Panel before the rising edge of the E enable signal
on the E pin.
Data - Read Only
This parallel interface data is input to the EP93xx
processor from the Smart Panel during a read cycle (see
RD bit in the
bits from the Smart Panel are loaded into this DAT field,
respectively, on the falling edge of the ‘E’ enable control
signal on the E pin.
Writing PIFEN = ‘1’ to the
the signals on these pins for Parallel Interface (Smart
Panel) operation:
V_CSYNC --> D7 (Smart Panel)
HSYNC --> D6
