6-5-2 MREAD
Note: P1, P2, ..., Pn: display data.
Put the RA8835 series into the data output state. Each time the microprocessor reads the buffer,
the cursor address is incremented by the amount set by CSRDIR and the next data byte fetched
from memory, so a sequence of data bytes may be read without further MREAD commands or by
updating the cursor address register. If the cursor is displayed, the read data will be from two
positions ahead of the cursor.
