6 / 34 page YSS944/943/940 6 Type Pin No. Pin Name I/O Note 1) Function 61 62 69 77 78 86 87 93 94 105 106 117 118 123 129 130 139 140 1 AHVSS Ground pin 2 for PLL analog block. Be sure to insert a 0.1 µF capacitor between the AHVDD and AHVSS pins. 2 AHVSSG Ground pin 3 for PLL analog block. Be sure to insert a 0.1 µF capacitor between the AHVDDG and AHVSSG pins. 3 DVSS Ground pin for PLL digital block. Be sure to insert a 0.1 µF capacitor between the DVDD and DVSS pins. 141 AVSSR Ground pin 1 for PLL analog block. Be sure to insert a 0.1 µF capacitor between the AVDDR and AVSSR pins. Initial clear 131 nIC Is Hardware reset input pin The LSI is initialized when this pin is at low level. 18 XI I Clock input pin. Connect this pin as shown in the circuit example Note 2) of the 12.288 MHz crystal oscillator. If not connected to a crystal oscillator, input a 12.288 MHz clock to this pin. Clock 19 XO O This is the output pin for the crystal oscillator. Connect this pin as shown in the circuit example Note 2). If not connected to a crystal oscillator and inputting directly to the XI pin, do not connect anything to this pin. Do not use this pin for any purpose other than clock oscillation. 126 nMICS Is This is the microprocessor interface’s chip select input pin. Input to the MISCK and MISI pins becomes valid when this pin is at low level. 125 MISCK Is This is the microprocessor interface’s clock input pin. 124 MISI I This is the microprocessor interface’s address read/write control and data input pin. Microprocessor interface 122 MISO Ot This is the microprocessor interface’s data output pin. Connect a pull-up resistor. 32 SDIMCK Is This is the master clock input pin for the audio interface’s input side. The master clock is input from DIR, ADC, etc. The highest clock frequency that can be input is 25 MHz. (The clock rate is 512 fs when the input sampling frequency is 48 kHz or less, 256 fs when the frequency is 96 kHz, and 128 fs when the frequency is up to 192 kHz.) Audio interface 31 SDIBCK Is This is the bit clock I/O pin for the audio interface’s input side. |
