So the sb (store byte) instruction will cause the strobe notWrB<n> to be asserted, where <n> is the address of the byte within its word (little endian). -- | Bob Wipfel Inmos Ltd, Bristol | EMail(UK) ukc!inmos!raw |----------------------------------------| or raw@inmos.co.uk | The opinions above are my personal | Internet: raw@inmos.com | views and do not reflect Inmos policy. | UUCP:(US) uunet!inmos.com!raw
