33 / 82 page  SMCxxxAF Card configuration 33/82 6.3 Pin Replacement register (base + 04h in attribute memory) This register contains information on the state of the READY signal when configured in memory mode and the IREQ signal in I/O mode. See Table 28 and Table 29. 6.3.1 CReady This bit is set to ‘1’ when the bit RReady changes state. This bit can also be written by the host. 6.3.2 CWProt This bit is set to '1' when the bit RWProt changes state. This bit can also be written by the host. 6.3.3 RReady This bit is used to determine the internal state of the Ready signal. In I/O mode it is used as an interrupt request. When written, this bit acts as a mask (MReady) for writing the corresponding bit CReady. 6.3.4 WProt This bit is always ‘0’ since the CompactFlash memory card does not have a Write Protect switch. When written, this bit acts as a mask for writing the corresponding CWProt bit. 6.3.5 MReady This bit acts as a mask for writing the corresponding CReady bit. 6.3.6 MWProt This bit when written acts as a mask for writing the corresponding CWProt bit.
