Description
Write Protect switch.
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.
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
Battery Voltage detection circuits on cards which
contain a battery. This signal represents the values on
PCMCIA pin BVD1. Also see Register 2Ch
(Table 54).
This bit is set to 1 when RWPROT changes state.
This bit is set to 1 when the bit RRDY//BSY changes
state.
This bit is set to 1 when the corresponding bit
RBVD2 changes state.
This bit is set to 1 when the corresponding bit
RBVD1 changes state.
