31.4.12.5 32-bit-read burst-inhibited from 8-bit port (no wait states)
The following figure shows a 32-bit read from an 8-bit device with burst inhibited. The
transfer results in four individual transfers. The transfer size is driven at 32-bit (00b)
during the first transfer and at byte (01b) during the next three transfers.
Note
There is an extra clock of address setup (AS) for each burst-
inhibited transfer between states S0 and S1.

31.4.12.6 32-bit-write burst-inhibited to 8-bit port (no wait states)
The following figure shows a 32-bit write to an 8-bit device with burst inhibited. The
transfer results in four individual transfers. The transfer size is driven at 32-bit (00b)
during the first transfer and at byte (01b) during the next three transfers.
