Figure 58 shows consecutive write operations using the WRDONEB signal without the READYB.
Write operations may only begin when WRDONEB is sampled low by the external interface. On
the first data transfer, the cycle is terminated normally. Subsequent access does not begin until
WRDONEB is sampled low by the external interface. This interface is used when the external
