If an address in the range 1010 to 1111 is speci- fied, the data on QD7 to QD0 is ignored. Note that writing to address 1001 also functions as the write stop command. - QD7 to QD0 (Q data setting and word data) The CD Q-channel has the general data format shown below. The write data required to fully specify the Q data is the 80 bits comprising CONTROL, ADR, and DATA-Q. The CRC write data is not required because it is generated by recalculation.

Next, only data that needs to be changed is written if the 91H command QRDY bit is 1, and then address 1001 is written again. Note that when shockproof mode is ON, the Q data is specified according to the data output from the SM5902AF. NIPPON PRECISION CIRCUITS-22 SM5902AF |
