PURPOSE:To enable the data conversion at input and output of data, by giving conversion table directly accessible, as to the data conversion with high usage frequency. CONSTITUTION:The output of an output register 101 is fed to I/O via the I/O bus 100, at the output without translation. The input data from the I/O bus 100 is received at an input register 102. The conversion table of data is written in the SPM memory 106 via a buffer 103. At data conversion, the converted data is set to an address register 104, and the conversion data corresponding to this data is read out from a memory 106. The gate 105 constitutes the address circuit to the memory 106. |
