Web15 okt. 2011 · 10-17-2011 10:21 AM. The IORD and IOWR macros treat the offset as a four byte word offset. Here are some examples: IOWR (0, 4, 1234). -> writes 1234 to base 0 + word offset 4 (byte address 0 + 4x4= 16) IORD (12, 2) -> reads from base 12 + word offset 2 (byte address 12+2x4 = 20) In general the byte offset is 'base + offset x 4'.
