Address multiplex size. Determines how the address of the current memory cycle can be output on the
address pins. This field is needed when interfacing with devices requiring row and column addresses
multiplexed on the same pins. See

Disable timer period. Guarantees a minimum time between accesses to the same memory bank controlled
by UPM n . The disable timer is turned on by the TODT bit in the RAM array word, and when expired, the UPM n
allows the machine access to handle a memory pattern to the same bank. Accesses to a different bank by
the same UPM n is also allowed. To avoid conflicts between successive accesses to different banks, the
minimum pattern in the RAM array for a request serviced, should not be shorter than the period established
by DS.
00 1-bus clock cycle disable period
01 2-bus clock cycle disable period
10 3-bus clock cycle disable period
11 4-bus clock cycle disable period
is selected to control the memory access.

LGPL4 output line disable. Determines how the LGPL4/LUPWAIT pin is controlled by the corresponding bits
in the UPM n array. See
Read loop field. Determines the number of times a loop defined in the UPM n will be executed for a burst- or
single-beat read pattern or when M x MR[OP] = 11 (
