12. STroBe / RESet Output
The STB/RST output pin is used to indicate the EM6605 RESET condition as well as write operations to ports B, C
and D. For a PortB, PortC and PortD write operation the STROBE signal goes high for half of the system clock
period. Write is effected on falling edge of the strobe signal and it can this be used to indicate when data changes
at the output port pins. In addition, any EM6605 internal RESET condition is indicated by a continuous high level on
STB/RES for the period of the RESET.
13. Test at EM - Active Supply Current test
For this purpose, five instructions at the end of the ROM will be added.
