The resulting timing pattern of the external bus signals is outlined in the following tables for read, write
and interleaved read/write accesses. Three examples represent different access lengths of 1, 2, and n–1 bus
cycles. Non-shaded bold entries denote all values related to Access #0.
The following terminology is used:

Bus cycle ->
ECLK phase
ADDR[22:20] / ACC[2:0]
ADDR[19:16] / IQSTAT[3:0] ...
ADDR[15:0] / IVD[15:0]
DATA[15:0] (internal read)
‘addr’ — value(ADDRx); small letters denote the logic values at the respective pins
‘x’ — Undefined output pin values
‘z’ — Tristate pins
‘?’ — Dependent on previous access (read or write); IVDx: ‘ivd’ or ‘x’; DATAx: ‘data’ or ‘z’
