Wake/runtime SCI events

Power sequencing control

2.5.10EFI Firmware Hub (FWH)

A TSOP socket houses the flash device (ST Microelectronics P/N# M50FW080) that stores the system EFI firmware. The EFI firmware can be programmed through a Microsoft MS-DOS* or Windows*-based utility.

2.5.11Trusted Platform Module (TPM) Header

Crown Beach implements a header at J9B4 to support TPM 1.2 specification compliant devices. The same header can be used for legacy connections, allowing other SIO solutions to provide floppy, COM, Parallel, and PS/2 functionality.

2.5.12SD/SDIO/MMC

Crown Beach provides three ports with the following features:

All ports are SD rev1.1 specification compliant and MMC rev4.0 specification compliant.

All ports operate to 48 MHz. Ports 0 and 1 support 4-bit operation. Port 2 supports 8-bit operation.

Slot 2 is also routed (with stuffing options) to the PCI Express* Mini Card for wireless solutions.

2.5.13Clocks

The Crown Beach CRB uses a CK-540 clock solution. The BSEL [2:1] signals driven by the processor are used by the CK-540 to configure the FSB frequency.

2.5.14Real Time Clock

An on-board battery maintains power to the real time clock (RTC) when in a mechanical off state (G3 state).
