pcmcia_status - 00_1006_1A70
READ ONLY, Read clears interrupt
Default
ext This bit reflects the state of the card detect 1 signal (PC_CD1_L) from the
PCMCIA card.
When both PC_CD1_L and PC_CD2_L are low the card is fully inserted.
ext This bit reflects the state of the card detect 1 signal (PC_CD1_L) from the
PCMCIA card.
When both PC_CD1_L and PC_CD2_L are low the card is fully inserted.
ext This bit reflects the state of the voltage sense 1 signal (PC_VS1_L) from
the PCMCIA card.
ext This bit reflects the state of the voltage sense 2 signal (PC_VS2_L) from
the PCMCIA card.
ext This bit reflects the state of the write protect signal (PC_WP) from the
PCMCIA card.
When high, write protect is enabled.
ext This bit reflects the state of the ready signal (PC_READY) from the
PCMCIA card.
When high, indicates the card is ready for access.
1'b0 When high, indicates 3 volt VCC is enabled. This bit reflects the value
driven on the PC_EN3V signal.
1'b0 When high, indicates 5 volt VCC is enabled. This bit reflects the value
driven on the PC_EN5V signal.
1'b0 This bit is set when either of the card detect signals change. It is cleared
by a read. If this bit is set an interrupt will be raised if it is not masked in
the pcmcia_cfg register.
1'b0 This bit is set when the write protect signal changes. It is cleared by a read.
If this bit is set an interrupt will be raised if it is not masked in the
pcmcia_cfg register.
1'b0 This bit is set when card ready signal changes. It is cleared by a read. If
this bit is set an interrupt will be raised if it is not masked in the pcmcia_cfg
register.
