16 bits
56-pin TSOP 16M bits flash ROM
Relocatable bank base address: C0000h,
C8000h,
D0000h,
D8000h, E0000h, and E8000h
Bank switch of 16KB block: Bank 512 to 895
17-2. Bank Base Address
The ROM disk area to be accessed is determined by inputting ad-
dress signals from the ISA bus.
The ROM disk area is base a (0000h-3FFFh) with the size of
16KB.
17-3. Bank Switch
For ROM bank 512 to 895, chip select and bank switch are performed
by issuing address signal BA0-6 and chip select signal FROS#0-2
from the PSC2.

Bank switch of 16KB block: Bank 0 to 191
Refresh: 2048 cycles/32ms (15.625us)
18-2. Bank Base Address
The RAM disk area to be accessed is determined by inputting ad-
dress signals from the ISA bus.
The RAM disk area is base a (4000h-7FFFh) with the size of
16KB.
18-3. Bank Switch
Chip select and bank switch are performed by issuing address signal
BA0-5 and chip select signal PRAS#0-2 from the PSC2.
19. Analog Touch Panel
19-1. Outline
The analog touch panel is controlled by Fujitsu’s control IC N010-
0559-V021, and the CPU issues commands to this panel through
serial interface.
Light load input type
Communication mode: Full duplex communication mode, serial inter-
face
Transmission rate: 9600 bps
Data transmission method: asynchronous start-stop synchronization
Signal level: TTL level
Data format: Binary
Bit form: Start bit (1) + data bit (8) + stop bit (1), non-parity
Interface signal: RXD/TXD
Sampling speed: 100pps maximum
20. Reset circuit
20-1. Bolck diagram
The RESETDRV in the PSC2 resets the ISA device in the PSC2.
The PHOLD is a control signal turning ON/OFF of AC input by the
software. The PHSNS is a sense signal.
