Description
Bit 0
Bit 1
RWPROT
Write Protect switch.
RRDY//BSY
When read, this bit represents the internal state of the
RRDY/BSY signal. When written, this bit acts as a
mark for writing the corresponding bit CRDY/BSY.
Bit 2
Bit 3
RBVD2
RBVD1
When read, this bit represents the internal state of the
Battery Voltage detection circuits on cards which
contain a battery. This signal represents the values on
PCMCIA pin BVD2. Also see Register 2Ch
(Table 54).
When read, this bit represents the internal state of the

(Table 54).
Bit 41
Bit 51
CWPROT
This bit is set to 1 when RWPROT changes state.
CRDY//BSY
This bit is set to 1 when the bit RRDY//BSY changes
state.
Bit 61
CBVD2
CBVD1
This bit is set to 1 when the corresponding bit
RBVD2 changes state.
Bit 71
This bit is set to 1 when the corresponding bit
RBVD1 changes state.
NOTES:
1. When this register is read, these four bits are reset.
