12 STroBe / ReSeT Output
The STB/RST output pin is used to indicate the EM6603 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 EM6603 internal RESET condition is indicated by a continuous
high level on STB/RST 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.
Testloop: STI
To stay in the testloop, these values must be written in the corresponding addresses before jumping in the loop:
Free space after last instruction: JMP 00H (0000)
Remark: empty space within the program are filled with NOP (FOFF).
