C-bus Select Pin
When using the PLL function, connect with R (1.5kΩ) and C (47nF) in
series and connected to analog ground (VSS1)
Connect a crystal oscillator between the XTI pin and XTO pin or input
an external clock into the XTI pin when not using a crystal oscillator.
Connect a crystal oscillator between the XTI pin and XTO pin or leave
open when using an external clock source.
Connect to VSS3
“L”: Normal Microcomputer Interface
“H”: I
Connect to VSS1
I2CSEL must be fixed to “L” (VSS3) or “H” (DVDD).
