The read values of these bits is always 0. These bits are not
affected by writing.
Indicates that Ready/Busy bit (bit 1) not changed (from 1 to 0
or from 0 to 1)
0 can be written to this bit only when this bit is 1 with bit 1 set
to 1.
Indicates that Ready/Busy changed (from 1 to 0 or from 0 to
1)
0 can be written to this bit only when this bit is 1 with bit 1 set
to 1.
The read value of this bit is always 0. This bit is not affected by
writing.
The read values of these bits is always 1. These bits are not
affected by writing.
Indicates card in busy state
Indicates card in ready state
In the IC memory card interface mode, such as power-on and
reset a High level is output (when a write operation to the
CCR is not performed).
The read value of this bit is always 0. This bit is not affected by
writing.
