Peripheral Channel Error for Device 3 (PCERR_SLV3) – Offset 4240
This register is used to control error reporting for the eSPI Peripheral Channel for the fourth eSPI device.
The register definition is identical to that of PCERR_SLV0, with the following exception:
Bit 28, SLV_HOST_RST_ACK_OVRD, has no impact since the Host_Reset_Ack VW from CS# > 1 is not supported by eSPI-MC (Host partition reset flow is gated only for CS0#).
