4 // File: host_811.c
5 // Purpose: 8051 firmware to master SL811 Embedded Host.
6 // Contains SL811-related control firmware.
7 // Based on SL811HST code written by cxn.
8 // H/W Target: SL811HST(Rev 1.5) + EZUSB DEV KIT
9 // IMPORTANT : Turn ON SW4 of S6-DIP-SWITCH
10 // to enable upper 32K memory on EZUSB Dev Kit
