3. Functional Description

3.1

Serial Interface

Data transfer starts with the falling edge of the CS signal. Data must appear at DI synchronized

to CLK and is accepted on the falling edge of the CLK signal. LSB (bit 0, SRR) has to be trans-

ferred first. Execution of new input data is enabled on the rising edge of the CS signal. When CS

is high, pin DO is in a tri-state condition. This output is enabled on the falling edge of CS. Output

data will change their state with the rising edge of CLK and stay stable until the next rising edge

of CLK appears. LSB (bit 0, TP) is transferred first.

Open load detection (low = on)

Programmable time delay for short circuit

(shutdown delay high/low = 12 ms/1.5 ms)

SCT

Software inhibit; low = standby, high = normal operation

(data transfer is not affected by standby function because the digital

part is still powered)
