P (Port Set)
[Function]
To display and modify the specified I/O set registers.
[Format]
P_aa_bb_cã (When setting R, D port)
aa
: I/O set register name
bb
: Specify in or out
c
: Set value (0 or 1)
P_aa_cc ã / P_aa_cã (when setting K)
aa
: I/O set register name
bb
: set value (one digit of a hexadecimal No.)
c
: Set value (0 or 1)
[Explanation]
The system sets the value in the specified I/O set register.
[e.g]
1) Example of setting K
>P K 8ã
> Pã
I/O Regs. Rin=0000 Rout=1111
>
D=00000000
OUT=0
K=1000(8h)
2) Example of K0-K3 setting
> P OUT 1ã
> P K1 1ã
>Pã
I/O Regs. Rin=0000 Rout=1111
>
D=00000000
OUT=1
K=0010(2h)
(I/O setting registers used on this simulator)
• Dout (D port output register 6 or 8 or 10bit)
• K (K input register 4bit)
• Rout (R port output register 4bit)
• Rin (R port input register 4bit)
• OUT (OUT port output register 10bit(
