Function
Secondary IDE Command Address Register:
This register specifies the amount of I/O space required for the secondary IDE command
registers. The IDE command block requires 8 bytes of I/O space (Bits [2:0] are hardwired to
001). Bits [15:3] are programmable. Bits [31:16] are hard-wired to 0000H. See stand-alone
description for 32-bit decode option description.
