Or, can be configured as a GPIO pin.
Clock input in slave mode or clock output in master mode. This pin can
be configured as an external clock buffer if I
used, this pin should be grounded).
Or, can be configured as a GPIO pin.
Word Select (WS) input in slave mode or WS output in master mode (If
I2S is not used, this pin should be grounded).
Or, can be configured as a GPIO pin.
Serial Data Output of the I
should be left unconnected).
Or, can be configured as a GPIO pin.
Digital power supply.
Digital Ground.
Digital Ground.
Digital power supply.
A 1.8V regulator to supply the internal logic. A 0.1uF capacitor should
be connected to this pin for supply decoupling and stability.
Master-In-Slave-Out. Serial output from the ISD15100 to the host. This
pin is in tri-state when SSB=1.
Serial Clock input to the ISD15100 from the host.
Slave Select input to the ISD15100 from the host. When SSB is low
device is selected and responds to commands on the SPI interface.
Master-Out-Slave-In. Serial input to the ISD15100 from the host.
Digital Power for the PWM Driver.
