DEC_CLOCK
Decoder master clock. All inputs and outputs are synchronized by the rising edge of DEC_CLOCK.
Input
119
DEC_CORR
Decoder message block corrected. Assertive HIGH. Indicates that errors have been found and
corrected in message block.
Output
24
DEC_DATARDY
Data Ready. Assertive HIGH. This output is held HIGH for data bytes and low check bytes.
Output
80
DEC_DATEN
Decoder data enable. Assertive HIGH. This input is used to signal the difference between data bytes
and check bytes.
Input
81
DEC_ENABIN
Decoder enable data correction. Assertive HIGH. When this input is asserted, the device performs
corrections on the message block. When CEN is low, the device does not perform corrections but
continues to report status is initialized to do so.
Input
120
DEC_EOB
Decoder End of Block. 1/0 = End/Not end of block.
Output
123
DEC_LOC
Decoder Error Location. Assertive HIGH. This output goes HIGH if the current symbol outout on
Q7-Q0 has had a correction applied to it.
Output
102
DEC_RESET
Decoder system reset. Assertive LOW. Reset timing is critical to the initialization of the device.
Input
40
DEC_STATEN
Status Enable. Asservie HIGH. If this signal is HIGH during reset then the decoder will be
programmed to output two status bytes with each message block.
Input
65
DEC_UNCORR
Decoder uncorrectable block. Assertive HIGH. Indicates message block contains uncorrectable errors.
