58 / 156 page  ALC5642-VF Datasheet Multi-Channel Audio Hub/CODEC with embedded Voice DSP and SounzReal TM Digital Sound Effect 46 Rev. 0.93 7.18. Programmable Register Array The Programmable Register Array is used for continuing executing register set by one register command. These registers are need to program first. There are 16-sequences register settings can be set. For each sequence, can fill in MX type registers, PR type register or time delay (100us ~ 100ms). These 16-sequences registers can be divided to two sequencers. The start point and end point for each sequencer can be set from sequence-0 to sequence-15. For example, you can program sequencer-1 to execute sequence-0 to sequence-10 and sequencer-2 to execute sequence-11 to sequence-15 or program sequencer-1 to execute sequence -6 to sequence -15 and sequencer-2 to execute sequence -0 to sequence -5. The Table 17 shown as programmable register table with two sequencers. Table 20. Programmable Register Table Sequencer (1-bit) Sequences (4-bit) Delay Time (8-bit) Register Level (1-bit) Register Index (8-bit) Register Data (16-bit) 1 Start 0000 ’b - x xx xxxx - 0001 ’b xx - - - - 0010 ’b - x xx xxxx - 0011 ’b xx - - - - 0100 ’b - x xx xxxx - 0101 ’b xx - - - End 0110 ’b - x xx xxxx 2 Start 0111 ’b xx - - - - 1000 ’b - x xx xxxx - 1001 ’b xx - - - - 1010 ’b - x xx xxxx - 1011 ’b xx - - - - 1100 ’b - x xx xxxx - 1101 ’b xx - - - - 1110 ’b - x xx xxxx End 1111 ’b xx - - - Settings Procedures: 1. Set Programmable Register Table => Set register level (MX-C8[9])/register index (MX-C8[7:0])/register data (MX-C9) for each sequence (MX-C8[15:12]) => Set delay time (MX-CA[15:8]) for each sequence (MX-C8[15:12]) => Set start point (MX-CB[11:8]/MX-CC[11:8]) and end point (MX-CB[3:0]/MX-CC[3:0]) for each sequencer 2. Enable Programmable Register Function (MX-CA[7]) 3. Execute Sequencer-1/2 => Sequencer-1 (MX-CA[6]) => Sequencer-2 (MX-CA[5]) 4. Check Sequencer-1/2 finished or not? => Sequencer-1 (MX-C8[11]) => Sequencer-2 (MX-C8[10]) |
