Required register settings and configuration items
•
The module uses one 32kx8 SRAM for all CG and display memory.
•
W/S, bit 3 of the P1 byte of the SYSTEM SET instruction, is set to 0 for
a single drive panel.
•
DR, bit 7 of the P1 byte of the SYSTEM SET instruction, is set to 0 to
turn off the additional output cycle of the shift clock
•
The recommended SYSTEM.SET parameter values are (P1 through
P8) in hex, for a frame rate of 240 Hz: 32, 07, 07, 1D, 23, 7F, 1E, 00.
•
P5 must not be less than 23 to guarantee that minimum line period
requirement of the display is achieved (32.5 µs)
•
The READY flag is high during extra line times, so P6 should be over
7F if the READY flag is used. After the falling edge of the READY flag
there is min. 3.5
µ
s time to end the display memory write cycle.
•
Oscillator frequency to RAiO RA8835A is 10 MHz
