Reading fromICR registers:
Ensure that the last value written to LCR was not 0xBF (see above).
Write 0x00 offset to SPR to select ACR.
Set bit 6 of ACR (ICR read enable) by writing x1xxxxxxb to address 101b. Ensure that other bits in ACR are not changed.
(Software drivers should keep a copy of the contents of the ACR elsewhere since reading ICR involves overwriting ACR!)
Write the desired offset to SPR (address 111b).
Read the desired value fromICR (address 101b).
Write 0x00 offset to SPR to select ACR.
Clear bit 6 of ACR bye writing x0xxxxxxb to ICR, thus enabling access to standard registers again.
