documentation on the out port

[hpwit]

hello great job first
could you please give me information about those ports oar any other ports
in the doc I have 40h,41h,11h,12h60h,61h,62h
thank you

6050PREPSR: LD A,2
6060 OUT (60H),A
6070 DEC A ; A=1
6080 OUT (74H),A
6090 XOR A ; A=0
6100 OUT (73H),A
6110 INC A ; A=1
6120 OUT (73H),A
6130 XOR A ; A=0
6140 OUT (73H),A
6150 LD A,0DH
6160 OUT (70H),A
6170 LD A,4EH
6180 OUT (71H),A
6190 LD A,10H
6200 OUT (71H),A
6210 XOR A ; A=0
6220 OUT (63H),A
6230 LD A,05H
6240 OUT (71H),A
6250 LD A,14H

Thank you for this fast answer
Do you have some here a documentation?
What is the port 1fh ? Is it to capture a key ?

[Kongduino]

1FH: 11Pin I/F input level Enter Break key

The Kon flag (bit 8, MSB) is set while pressing the Break key.

I have various references, they need to be compiled together. I'll try to work on something.

hello
Have you had time to have a look at it ?
thank you
would you happen to know if you can attach an interrupt to on of the input pin ?

[Kongduino]

Hi, too busy to do anything about the docs right now. There's no interrupt for the 11-pin, but you can simulate that. In PIO mode (write 1 to port 60H: PIO mode, and 1 to 61H PIO input) you can read port 62H to get the state of the 8 pins in a loop.

There's an interrupt on the 11-pin, but we don't have access to it – it's for the system itself.
