Digital Ground.
Digital power supply.
A 1.8V regulator to supply the internal logic. A minimum 1uF
capacitor with low ESR<0.5OHM should be connected to this pin for
supply decoupling and stability.
Master-In-Slave-Out. Serial output from the ISD3800 to the host.
This pin is in tri-state when SSB=1.
Can be configured as GPIO1.
Serial Clock input to the ISD3800 from the host.
Slave Select input to the ISD3800 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 ISD3800 from the host.
Can be configured as GPIO0.
