Section 8 Bus Controller (BSC)
8.9.5
The bus cycle in the address/data multiplexed I/O interface consists of an address cycle and a data
cycle. The data cycle is based on the basic bus interface timing specified by the ABWCR,
ASTCR, WTCRA, WTCRB, RDNCR, and CSACR.
Figures 8.30 and 8.31 show the basic access timings.
