TLE75620-EST

SPIDER+ 12V

Control Pins

The device has three pins (IN0, IN1 and IDLE) to control directly the device without using SPI.

5.1

Input pins

TLE75620-EST has two input pins available. Each input pin is connected by default to one channel (IN0 to

channel 2, IN1 to channel 3). Input Mapping Registers MAPIN0 and MAPIN1 can be programmed to connect

additional or different channels to each input pin, as shown in Figure 10. The signals driving the channels are

an OR combination between OUT register status, PWM Generators (according to PWM Generator Output

Mapping status), IN0 and IN1 (according to Input Mapping registers status). See Chapter 7.5 for further

details.

Figure 10 Input Mapping

The logic level of the input pins can be monitored via the Input Status Monitor Register (INST). The Input

Status Monitor is operative also when TLE75620-EST is in Limp Home mode. If one of the Input pins is set to

“high” and the IDLE pin is set to “low”, the device switches into Limp Home mode and activates the channel

mapped by default to the input pins. See Chapter 6.1.5 for further details.

5.2

IDLE pin

The IDLE pin is used to bring the device into Sleep mode operation when is set to “low” and all input pins are

set to “low”.When IDLE pin is set to “low” while one of the input pins is set to “high” the device enters Limp

Home mode.

To ensure a proper mode transition, IDLE pin must be set for at least tIDLE2SLEEP (P_6.3.54, transition from “high”

to “low”) or tSLEEP2IDLE (P_6.3.53, transition from “low” to “high”).

Setting the IDLE pin to “low” has the following consequences:

• All registers in the SPI are reset to default values
