7545 Group
MISRG
The 7545 Group has two power source supply pins. One is the
VCC pin, and the other is the VDDR pin only for RAM2. A
potential difference between VCC and VDDR may cause some
failures in reading from RAM2 o r wr iting to RAM2.
Accordingly, if there is a potential difference between VCC and
VDDR at power-on, confirm the bit 1 (RAM2 status flag) of
MISRG (address 003816) before reading from RAM2 or writing
to RAM2.
