5.3.3. ROM (IC2)
This 128 KB ROM (OTPROM or MASKROM) has 32 KB of common area and bank area
(BK4~BK15). / The capacity of each bank is 8 KB. / The addresses of the common area are from
0000H to 7FFFH, and addresses 8000H to 9FFFH are for the bank area.
5.3.4. RAM (IC3)
This 32 KB RAM has 8 KB of common area and bank area (BK0, BK1). / The capacity of each
bank is 12 KB. / The addresses of the common area are from D000H to EFFFH, and addresses
A000H to CFFFH are for the bank area.
5.3.5. RESET CIRCUIT
The output from pin 1 of the Reset IC (IC4) resets the gate array (IC1).
During a power surge, a positive reset pulse of 175 msec or more is generated and the system
is reset completely. / This is done to prevent partial resetting and system runaway during a
power fluctuation.
When pin 1 of IC4 becomes low, it will prohibit the RAM (IC3) from changing data. / The RAM
(IC3) will go into the backup mode, when it is backed up by a lithium battery.
