LM9830 can correct for using its internal PGA.
Note 13:
Note 14: Interaction with an actual parallel port load (C
For this reason, it is recommended that the parallel port be driven to 0x00h by the PC when not in the reverse transfer phase. When reading coefficient data from register 6
(register 3 = 00000XX1 binary), the EPP handshaking generated by the host PC may be faster than the data can settle. For this reason it is recommended that software
handshaking (“PS2” mode) be used when verifying coefficient data.
