PCMCIA Interface
TS102 Registers
request is not automatically masked when the card is not
I/O. The interrupt request should normally be explicitly
masked when the card is not I/O using the interurpt mask bit
in the card interrupt register.
Bit 11
LVL – IRQ Leve/Edge Control. This bit controls whether
the card IRQ input is edge or level sensitive. By default it is
edge sensitive.
0 = edge sensitive
1 = level sensitive
Bits 10:9
BVD(1:0) – Battery Voltage Detect. These bits indicate the
status of the card battery voltage detect bit. These are not
valid for an I/O card, and the battery voltage status may be
read from the card pin replacement register, if these bits are
implemented in the card.
00 = battery low, data suspect
01 = battery low, data suspect
10 = battery low, data OK
11 = battery good
Bit 8
WP – Write Protect. The WP bit indicates that the card is
write protected, as the card has its WP signal asserted.
Bits 7:6
Vpp2(1:0) – Programming Voltage Control
Bits 5:4
Vpp1(1:0) – Programming Voltage Control. The Vpp1 and
Vpp2 bits control the Vpp1 and Vpp2 voltages, and allow
them to be set to:
00 = 0V
01 = Vcc (5V or 3.3V)
10 = Vpp (12V)
11 = NC
Bit 3
Vcc – The Vcc bit controls the card Vcc voltage, allowing it
to be set to either 5V or 3.3V:
0 = 5V
1 = 3.3V
Bit 2
TYP3 – The TYP3 bit configures the card as a disk. This
may not be implemented if Type-3 PCMCIA data is not
available.
Bit 1
IO – The IO bit controls whether the card is configured for
I/O or memory:
