  • Microcomputer command read/write Data (MSD) is read at a rising edge of the clock pulse (MCK). When a command is determined at a falling edge of the latch line (MLAB), the data line (MSD) is concurrently switched to the output mode to output a status requested by data bits D3, D2, D1 and D0. When the latch line is set to "H", the data line is returned to the input mode again.
  • Status request/interface command When requesting various types of the M65824FP status, a microcomputer writes data in D3, D2, D1 and D0 for indicating the requested status in advance. After this command is latched, the status is continuously output while the latch line (MLAB) is set to "L".

  • SBQS is set to "L" when both the following two conditions are satisfied at the same time. (a) CRC check OK (b) When the two subcode syncs (S0, S1) are normal
