The Universal Programming Box (UPB) has a Control Line Test that can be run by Flashwizard. However, it does not test all of the CS lines, RD WR and other control lines that one would expect it would.

The Control Line Test was reimplemented in FlashWizard using a low level function of the UPB that allws Flashwizard to turn IO pins on and off.

These are the signals that are now tested. UCS, CS0, CS1, CS2, CS3, CS4, CS5, CS6, W/R, RD, WR, BLE, BHE, LBA, P1.0, P1.2, P1.3, P1.4, P1.5, P1.6, P1.7, ADS, P3.0, P3.1, P3.6, RTS0, TX0, RTS1, TX1.

Additional Logic was added in order to convince the CPLD to activate 3CS1B as well as 3CS1A by using A21 and activating UCS1 twice.

Address and Data Lines are tested in the Address and Data Line Tests.
