The WKUP_ESM0, MCU_ESM0, and ESM0 modules are hereinafter referred to as ESM module.
This section describes the ESM external connections (environment).
Figure 12-2944 shows the ESM pins used for typical connections with external devices.
Table 12-5639 describes the ESM I/O signals.
Module Pin | Device Level Signal | I/O(1) | Description | Module Pin Reset Value(1) |
---|---|---|---|---|
WKUP_ESM0 | ||||
ERR_O | MCU_SAFETY_ERRORn | O | Active low error output signal. | 0(2) |
MCU_ESM0 | ||||
ERR_O | MCU_SAFETY_ERRORn | O | Active low error output signal. | 0(2) |
ESM0 | ||||
ERR_O | SOC_SAFETY_ERRORn | O | Active low error output signal. | 0(2) |
For more information about device level signals (pull-up/down resistors, buffer type, multiplexing and others), see tables Pin Attributes and Pin Multiplexing in the device-specific Datasheet.
