Power ground
SCLK
4
I
Data shift clock. Note that the internal connections are switched by MODE (pin #30). At
SCLK↑, the shift-registers selected by MODE shift the data.
SIN
5
I
Data input of serial I/F
SOUT
28
O
Data output of serial I/F
VCC
32
Power supply voltage
XERR
29
O
Error output. XERR is open drain terminal. XERR gets L when LOD or TEF detected.
XLAT
3
I
Data latch. Note that the internal connections are switched by MODE (pin #30). At XLAT↑, the
latches selected by MODE get new data.
