Appendix E
Memory Access Timing
Table E-1
clock values show the number of clocks from the moment an address is valid on a specific bus, until data
is back on that same bus. The following assumptions were used when compiling the information:

N is the number of read cycle clocks from external address valid till external data valid. In the case of zero wait states, N
= 2.
Assuming BBC is parked on the U-bus
SIUMCR[BURST_EN] = 1
Until address is valid on external pins
“/” indicates on/off page Flash access.
The arbitration time was ignored. The values assume that the bus (or buses) involved in a
transaction was in the IDLE state when the transaction needs that bus.
The UIMB works in a mode of 1:1. This is relevant for IMB access values. In the case of 2:1 mode,
the clock latency for a cycle on the IMB should be doubled (each IMB access takes two clocks).
The basic delay of an external bus to a U-bus is four clocks (external master case).
All IMB accesses are assumed to be 16-bit accesses only. If 32-bit accesses are used, then each such
IMB access is split into two separate 16-bit cycles with normal IMB performance for each.
