1) These bits are automatically cleared on an over-temperature event.
2) These bits are automatically cleared upon SLEEP or STANDBY Mode entry.
3) This bit is gated in case a failure event (OC, OV, UV) is captured in an interrupt flag (see Figure 3.19).
3.11.3. ECM Driver Output Diagnostic Check
The ECM driver diagnostic circuitry is able to detect open/short failures in the driver output. The diagnostic
functionality is controlled and monitored by register ECMDIAG (Table 3.29 and Table 3.30).
Table 3.31 gives the meaning of the ECMOSF bit in the ECMDIAG register with respect to the combination of
ECMCSHEN and ECMCSLEN bits that enable the diagnostic current sources/sinks connected to the EC_M and
AC_RES pins respectively.

1) The ECMOCIF is physically implemented in register ECMDIAG and mapped to IRQSTAT (Table 3.10).

Bit Description
7:4 Unimplemented bits. Read as 0.
ECMCSHEN⁽¹⁾: ECM high-side current source enable bit.
3 1 = High-side current source is enabled.
0 = High-side current source is disabled.
ECMCSLEN⁽¹⁾: ECM low-side current source enable bit.
2 1 = Low-side current source is enabled.
0 = Low-side current source is disabled.
1
ECMSOF: Open/short status flag of the ECM driver. This flag is not registered; i.e., its value remains as long as the
diagnostic event takes place (see Table 3.31).
