//           Sample program  SineWave.eve
//
// This is the program for outputting the sine wave by using SIN ROM.
// The value of CNT0 is incremented and transfered to SIN ROM address
// (ROMA). The sine wave data from SIN ROM (ROMD) is output from SDO0
// Lch.
// The frequency of the sine wave is fs/64.
//
// SineWave.datEve is assemble from this program by executing EveAsm.exe.
