Logic Card Jumpers
See MAP 050 for the jumper locations on the following
cards:
The following examples and the illustration show how to
locate certain registers within the various levels. Note that
the bytes are displayed vertically. Use the numbers in lines
5 and 6 to help you locate the registers in each level.

The BSCA jumpering information is found in the IBM
5110 Binary Synchronous Communications Feature
Maintenance Information Manual, SY31'()558. The remaining level 1 registers contain hex DDDD.
DISPLAY REGISTERS
To display the hex registers and the read/write storage size,
the DISPLAY REGISTERS switch must be in the DIS-
PLAY REGISTERS position. This displays the first 512
bytes or 256 halfwords of storage. The first 64 halfwords
are the registers.

The remaining level 3 registers contain hex BBBB.
Register
Level Use
The 64 registers (halfwords) are divided into 4 levels (0, 1, •
2, and 3) consisting of 16 registers each (O-F). The MAPs
refer to the registers and levels in an abbreviated manner;
for example, R 1 L2 means register 1, level 2.
The position of the L32-64-R32 switch determines the num-
ber of registers displayed. In the L32 position, the 32 regis-
ters in levels 0 and 2 are displayed. Likewise, in the R32
position, the 32 registers in levels 1 and
3
are displayed. To
display all 64 registers, move the switch to 64.
