9 / 24 page  INTEGRATED CIRCUITS INC.-- APR6016 http://www.aplusinc.com.tw / 24 TEL : 886-2-2782-9266 ver1.4 9 Reading the SID Each device in the APRXX series family contains an embedded Silicon Identification (SID). The SID can be read by the host processor to identify which family/family member is being used. Reading the device SID requires issuing two OpCode commands; a SID command followed by any other command,usually a NOP command. The device will clock the SID data out on the DO pin as the command that follows the SID command is clocked in. Figure 9 is a diagram that describes the process necessary for reading SID information. The SID information follows the format given in Figure 10. The first bit shifted out DO is the Overflow bit. The Overflow bit is set to a binary 1 if an attempt was made to record beyond the available memory. The Overflow bit is set to 0 if an overflow has not occurred. This bit is cleared after it has been read. The Dl bit is the End Of Data (EOD) bit. The EOD bit is set when the device stops playing or fast-forwarding as a result of EOD bit in memory. The EOD bit cleared after it has been read. The D2 bit is the Illegal Address bit. The Illegal Address Bit is set whenever an illegal address is sent to the device. The D3 bit is the LBAT bit. This bit is set when the device senses a supply voltage below specification. The following five bits represent the product family. The APRXX product family code is binary 01000 as shown in Figure 10. The next four bits represent the device code. The APR6016 device code is binary 0010 as shown in Figure 10. The last seven bits are random data and should be ignored. |
