DM634 Serial Data Interface The serial-in data (DAI) will be clocked into 16 × 16 bit shift registers synchronized on the rising edge of the clock (DCK). The data will be transferred into the 16 × 16 bit latch registers when the strobe signal ( LAT ) is kept at high level (level trigger); otherwise, the data will be held. The latch pulse should be sent after the falling edge of the last clock within a frame data. The trigger timing of the serial-out data (DAO) will be shifted out on synchronization to the rising edge of the clock if serial out selection (SOMODE) is kept at low level. And if serial out selection (SOMODE) is kept at high level, the serial-out data (DAO) will be shifted out on synchronization to the falling edge of the clock (DCK). Input Data Format Serial-out Data Format D15 [15] THF D15[13] D15[10] D15[9] D15[8] D15[12] D15[11] D15[7] D15[6] D15[5] D15[2] D15[1] E[15] D15[4] D15[3] LSB OUT 15 MSB shift out first LSB OUT 14 MSB LSB OUT 0 MSB D 14[15] D 14[14] D 14 [13] D 14 [10] D 14[9] D 14[8] D 14 [12] D 14[11] D 14 [7] D 14[6] D 14[5] D 14[2] D 14[1] E[14] D 14[4] D 14 [3] D 0 [15] D 0 [14] D 0[13] D 0[10] D 0 [9] D 0 [8] D 0[12] D 0 [11] D 0[7] D 0 [6] D 0 [5] D 0 [2] D 0 [1] E[0] D 0[4] D 0[3] * E[15], E[14], ... E[ ] 0 are Error Messages of LED Open Detection. `1'is normal, and `0'is abnormal. * THF is the Error Message of chip thermal detection. `1'is normal, and `0'is abnormal. |
