M x MR[GPL4].
If M x MR[GPL4] = 0 and LGPL4/LUPWAIT pin functions as an output (LGPL4), G4T1/DLT3
defines the state (0 or 1) of LGPL4 during bus clock quarter phases 1 and 2 (first half phase).
If M x MR[GPL4] = 1 and LGPL4/LUPWAIT functions as an input (LUPWAIT), if a read burst or
single read is executed, G4T1/DLT3 defines the sampling of the data bus as follows:
0 In the current word, the data bus should be sampled at the start of bus clock quarter phase
1 In the current word, the data bus should be sampled at the start of bus clock quarter phase
If M x MR[GPL4] = 0 and LGPL4/LUPWAIT pin functions as an output (LGPL4), G4T3/WAEN
defines the state (0 or 1) of LGPL4 during bus clock quarter phases 3 and 4 (second half phase).
If M x MR[GPL4] = 1 and LGPL4/LUPWAIT functions as an input (LUPWAIT), G4T3/WAEN is
used to enable the wait mechanism:
0 LUPWAIT detection is disabled.
1 LUPWAIT is enabled. If LUPWAIT is detected as being asserted, a freeze in the external

Loop start/end. The first RAM word in the RAM array where LOOP is 1 is recognized as the loop
start word. The next RAM word where LOOP is 1 is the loop end word. RAM words between,
and including the start and end words, are defined as part of the loop. The number of times the
UPM executes this loop is defined in the corresponding loop fields of the M x MR.
0 The current RAM word is not the loop start word or loop end word.
1 The current RAM word is the start or end of a loop.
Note: AMX must not change values in any RAM word which begins a loop
