Module Slot Location Bits. These bits identify the slot location
of the AP module in a system. The Carrier may use backplane
signals as in a VPX system or a carrier DIP switch to uniquely
identify the system location of the carrier.

System Slot identification bits are described by the
AcroPack carrier card.
31 to 8 Not Used
Digital Input/Output Registers (Read/Write) - (BAR1 + 0x0000 0008)
APZU-301
Twenty eight possible low voltage TTL input/output channels numbered 0
through 27 may be individually accessed via these registers. The
Input/Output Digital register is used to monitor/read or set/write channels 0
through 27. Channels 0 to 27 are accessed at the carrier base a
0x0000_0008 via data bits 0 to 27.
The unused upper 4 bits of this register are “Not Used” and will always read
low (0’s).
APZU-303
Twenty possible input/output channels numbered 0 through 19 may be
individually accessed via these registers. The Input/Output Digital register is
used to monitor/read or set/write channels 0 through 19. Channels 0 to 19
are accessed at the carrier base a 0x0000_0008 via data bits 0 to 19.
The unused upper 12 bits of this register are “Not Used” and will always
read low (0’s).
APZU-304
Fourteen possible LVDS input/output channels numbered 0 through 13 may
be individually accessed via these registers. The Input/Output Digital
register is used to monitor/read or set/write channels 0 through 13.
Channels 0 to 13 are accessed at the carrier base a 0x0000_0008 via
data bits 0 to 13.
The unused upper 18 bits of this register are “Not Used” and will always
read low (0’s).
Channel read/write operations use 8-bit, 16-bit, or 32-bit data transfers with
the lower ordered bits corresponding to the lower-numbered channels for
the register of interest. All input/output channels are configured as inputs
on a power-on or software reset.
Digital Direction Control Register (Read/Write) - (BAR1 + 0x0000 000C)
APZU-301
The data direction (input or output) of the 28 low voltage TTL digital
channels is selected via bits-0 through 27 of this register.
APZU-303
The data direction (input or output) of the 20 TTL digital channels is selected
via bits-0 through 19 of this register.
