Enhanced Local Bus Controller
13.4.4.3
RAM word fields specify the value of the various external signals at a granularity of up to four values for
each bus clock cycle. The signal timing generator causes external signals to behave according to timing
specified in the current RAM word. ach bit in the RAM word relating to LCSn and LBS timing specifies
the value of the corresponding external signal at each quarter phase of the bus clock.
The division of UPM bus cycles into phases is shown in
13.4.4.4
The RAM array for each UPM is 64 locations deep and 32 bits wide, as shown in
at the bottom of the figure are UPM outputs. The selected LCSn is for the bank that matches the current
address. The selected LBS is for the byte lanes read or written by the access.
13.4.4.4.1
The RAM word is a 32-bit microinstruction stored in one of 64 locations in the RAM array. It specifies
timing for external signals controlled by the UPM.
and BSTn bits determine the state of UPM signals LCSn and LBS[0:3] at each quarter phase of the bus
clock.
