Downbond Ground
Input M Counter bit0 (LSB).
Input M Counter bit1.
Input M Counter bit2
Input M Counter bit3.
Input M Counter bit4.
Input
Serial load enable input. While S_WR is “low”, Sdata can be serially clocked. Primary
register data are transferred to the secondary register on S_WR rising edge.
Input M Counter bit5.
Input Binary serial data input. Input data entered MSB first.
Input M Counter bit6.
Input
Serial clock input. SDATA is clocked serially into the 21-bit primary register (E_WR “low”) or
the 8-bit enhancement register (E_WR “high”) on the rising edge of Sclk.
Input M Counter bit7.
Input M Counter bit8 (MSB).
Input A Counter bit0 (LSB).
Input A Counter bit1.
Input
Enhancement register write enable. While E_WR is “high”, Sdata can be serially clocked
into the enhancement register on the rising edge of Sclk.
Input A Counter bit2.
Input A Counter bit3 (MSB).
Input Direct mode select. “High” enables direct mode. “Low” enables serial mode.
Input Prescaler enable, active “low”. When “high”, Fin bypasses the prescaler.
(Note 1) Digital core V_DD.
