DRQ_SRC — DRQ Source Register (R/W)

Reset Value: 00000000h

Note:

DRQx are internal signals between the Core Logic and SuperI/O modules. Some signals require additional programming to
make them externally accessible. See Table 4-2 "Pin Multiplexing, Interrupt Selection, and Base Address Registers" on page
72 for pin multiplexing details and Table 3-4 "Strap Options" on page 44 for LPC_ROM strap information.
