Address Straps: When the Intel, Motorola, or Multi-
plexed ( P1 is high and P0 is low) microprocessor
interfaces are selected, the two address straps, S7
and S6, allow the M13X to be partitioned as a seg-
ment of memory. The straps define the address offset
of the device. The address register is partitioned as
shown below. The data register pointed to by the 6
least significant bits is only accessed if the 2 most sig-
nificant bits match the address straps.
Address register partition for Intel, Motorola, or Multi-
plexed ( P1 is high and P0 is low) microprocessor
interfaces:
When the multiplexed microprocessor interface is
selected, by setting P1 high and P0 high, the three
address straps, S7, S6, and S5, allow the M13X to be
partitioned as a segment of memory. The straps
define the offset of the device. The address register is
partitioned as shown below. The data register pointed
to by the five least significant bits is only accessed if
the three most significant bits match the address
straps.
Address register partition for the multiplexed micropro-
cessor interface when P1 is high and P0 is high:
Address Bus (Intel/Motorola):
Multiplexed - These leads are disabled when the multi-
plexed interface is selected.
Intel/Motorola - These are active high address line
inputs that are used by the microprocessor for access-
ing the M13X registers for a read/write cycle. A7 is the
most significant bit.
Motorola):
Multiplexed - These bidirectional leads constitute
address/data buses for accessing the M13X registers.
Intel/Motorola - These bidirectional leads are used
only for transferring data.
The most significant bit is A/D7 or D7.
