The addresses of each register listed in this table are defined as a relative offset to the host “Base Address” defined in the EC-Only Register Base Address Table. The Base Address indicates where the first register can be accessed in a particular address space for a block instance. 9.10.1 HOST-TO-EC MAILBOX REGISTER Offset 0Ch Bits Description Type Default Reset Event 7:0 APPLICATION_ID When this field is 00h it can be written with any value. When set to a non-zero value, writing that value will clear this register to 00h. When set to a non-zero value, writing any value other than the cur- rent contents will have no effect. R/W 0h VCC1_R ESET Block Instance Instance Number Host Address Space Base Address EMI 0 EC 32-bit internal address space 400F_0100h Offset Register Name (Mnemonic) 00h HOST-to-EC Mailbox Register 01h EC-to-HOST Mailbox Register 04h Memory Base Address 0 Register 08h Memory Read Limit 0 Register 0Ah Memory Write Limit 0 Register 0Ch Memory Base Address 1 Register 10h Memory Read Limit 1 Register 12h Memory Write Limit 1 Register 14h Interrupt Set Register 16h Host Clear Enable Register Offset 00h Bits Description Type Default Reset Event 7:0 HOST_EC_MBOX 8-bit mailbox used communicate information from the system host to the embedded controller. Writing this register generates an event to notify the embedded controller. The embedded controller has the option of clearing some or all of the bits in this register. This is dependent on the protocol layer imple- mented using the EMI Mailbox. The host must know this protocol to determine the meaning of the value that will be reported on a read. This bit field is aliased to the HOST_EC_MBOX bit field in the HOST-to-EC Mailbox Register. R/WC 0h VCC1_R ESET |
