Compatible with MSB / LSB justified 24, 20 and 16 bits. Normally connected
to Bluetooth line (receiving).
Compatible with MSB / LSB justified 24, 20 and 16 bits. This pin changes to
a conditional jump pin (JX3) by setting control register (JX3_E) to “1”.
A conditional jump pin (JX2) is available by setting control register (JX2_E)
to “1”.
A conditional jump pin (JX1) is available by setting control register (JX1_E)
to “1”.
A conditional jump pin (JX2) is available by setting control register (JX0_E)
to “1”.
Normally connected to the Bluetooth Data Clock line (256kHz/512kHz).
Normally connected to the Bluetooth Sync Clock line (8kHz).
Use to initialize the AK7753. When changing CKM [3:0] and changing XTI
or BITCLK_I input frequency, it is necessary to set this pin.
When changing CKM[3:0] and XTI or BITCLK_I input frequency without
using INIT_RESET_N, it is necessary to set this pin. The control register
CKRST has the same function.
The output frequency is selected by a control register.
