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 or Hop_WR rising edge.
M Counter bit5.
Binary serial data input. Input data entered MSB first.
M Counter bit6.
Serial clock input. SDATA is clocked serially into the 20-bit primary register (E_WR “low”) or
the 8-bit enhancement register (E_WR “high”) on the rising edge of Sclk.
M Counter bit7.
M Counter bit8 (MSB).
A Counter bit0 (LSB).
A Counter bit1.
Enhancement register write enable. While E_WR is “high”, Sdata can be serially clocked into
the enhancement register on the rising edge of Sclk.
A Counter bit2.
A Counter bit3 (MSB).
Direct mode select. “High” enables direct mode. “Low” enables serial mode.
Prescaler enable, active “low”. When “high”, Fin bypasses the prescaler.
