C Control Data Clock Pin, (when the SPB pin= “H”)
When the PDN pin = “L”, the SDRO3 pin outputs “L”.
When the PDN pin = “L”, the SDTO2 pin outputs “L”.
When the PDN pin = “L”, the SDTO1 pin outputs “L”.
When the PDN pin = “L” in master mode, the OBOCK pin outputs “L”.
When the PDN pin = “L” in master mode, the OBOCK pin outputs “L”.
When the PDN pin = “L”, XTO outputs Hi-z.
When the PM2 pin = “H” and PDN pin = “L”, the MCKO pin outputs “L”.
When the PM2 pin = “L” and PDN pin = “L”, the MCKO pin outputs Hi-z.
This pin must be connected to VSS2-5 in parallel control mode (SPB pin = “L”).
Since there is a protection diode between this pin and DVDD1-4, connect pulled-up
resister to DVDD1-4 + 0.3V or less. This pin must be connected to the VSS2-5 in
parallel control mode (PSB pin= “L”).
