• Host Domain:

LPC, PNPCFG logic device, host parts of SMFI/SWUC/KBC/PMC logical devices and host parts of EC2I.

• EC Domain:

EC 8032, INTC, WUC KB Scan, GPIO, ECPM, SMB, PS/2, DAC, ADC, PWM, HWS, ETWD, EC2I,

GCTRL, BRAM, EGPC, DBGR, EC parts of SMFI/SWUC/KBC/PMC and EC parts of EC2I.

• Double-mapping Module:

BRAM, SSPI and UART1

Note:

There are three SPI functions in EC. Two of them are masters and one is slave.

1. SPI memory master (abbreviated as FSPI) is connected to the SPI flash.

2. SPI master (abbreviated as SSPI) is connected to the slow (contrast to SPI flash) SPI slave(s).
