6 / 178 page  FEDL22Q53X-02 ML22Q53X Pin Symbol I/O Attribute Description Initial value *1 43 RESETB I Negative Reset input pin. The LSI is initialized by the "L" level input. After a reset is input, all the circuits stop operating and enter the power-down state. At power-on, input an "L" level to this pin. After the power supply voltage stabilizes, set this pin to an "H" level. A pull-up resistor is internally connected to the LSI. ( *2) 44 TEST0 I Positive Input pin for testing. A pull-down resistor is internally connected to the LSI. Fix to the DGND. L 45 STATUS1 O - Status/error output pin 1. Execute OUTSTAT command to select BUSYB *3 and NCR*3 in each channel, or errors. The initial value is BUSYB *3 of channel 0, and output data is "H" level. H 46 STATUS2 O - Status/error output pin 2. Execute OUTSTAT command to select BUSYB *3 and NCR*3 in each channel, or errors. The initial value is BUSYB *3 of channel 0, and output data is "H" level. H 47 CBUSYB O Negative Command processing status signal output pin. An "L" level is output during command processing. Be sure to input a command with this pin at an "H" level. ( *2) 12,37, 38,41, 42,48 N.C. - - Unused pin. Leave open. Hi-Z *1 Initial value at reset input and power-down. The pin whose IO is "I" indicates a fixed level from outside. *2 "L" at reset, "H" at power-down *3 For NCR, BUSYB, refer to the description of "RDSTAT command". ■ Termination of Unused Pins This section explains how to terminate unused pins. Symbol Recommended pin termination SCL Connect to the DVDD. SDA SAD0 Connect to the DGND. SAD1 SAD2 LRCLK Connect to the DGND. BCLK SAI_IN CSB Connect to the DVDD. SCK Connect to the DGND. SI IRON Connect to the DGND. XT Leave open. XTB FB1 Connect to the SPGND. FB2 AIN Connect to the SPGND. TEST0 Connect to the DGND. N.C. Leave open. SAI_OUT Leave open.
