Explanation of input/output signal
Input/output signals are /CLD,/RCL,/RDT, and effective operation mode for each of these signals
shall be “L” level for all.
(1) /CLD
The /CLD line will be low when a Magnetic Card is inserted in the
(CARD LOAD) end of Magnetic Card Reader.
The /CLD line will be Low at all othr times
(2) /RCL1, /RCL2
This is used to sample the data line by it's falling edge.
(READ CLOCK)
(3) /RDT1, /RDT2
The moment /RCL changes from High to Low ; /RDT is “1”
(READ DATA) when the (/RDT1, /RDT2) /RDT line is Low , and /RDT is “0”
when the /RDT line is High.
