This procedure takes following action when it is called.
1. Initialize NEC7210.
2. Set relative parameters in NEC7210 and working RAM.
3. Set NEC7210 I/O address, IRQ and DMAchannel.
PROGRAM EXAMPLES:
1)
Set operation mode to: Non-system controller, No IRQ,
No DMA. Bus address is 21. I/O port address is 0x2B8
Hex
•
•
ioport,myaddr,setting : integer;
•
ioport:=16#2B8; { or $2B8 for Turbo Pascal }
myaddr:=21;
setting:=16X20; { or $20 for Turbo Pascal, bit 5:=1}
ieinit(ioport,myaddr,setting);
•
•
2)
Set operation mode to: System controller, IRQ7, DMA1.
Bus address is 0. I/O port address is 0x3C8
Hex.
•
•
ioport,myaddr,setting : integer;
•
ioport:=16#3C8; { or $3C8 for Turbo Pascal }
myaddr:=21;
setting:=16#1D; { or $1D for Turbo Pascal, bit
ieinit(ioport,myaddr,setting);
•
•
3)
Set operation mode to: System controller, No IRQ, DMA2
with block transfer, fast speed. Bus address is 21. I/O port address is 0x2B8
Hex.
•
•
loport,myaddr,setting : integer;
ioport:=16#2B8; {or $2B8 for Turbo Pascal}
myaddr:=21;
setting:=16#5002; { or $5002 for Turbo Pascal, bit
1,12,14:=1}
