CANCEL_ACCESS
For write operations, 32 data bits must be provided, or the result will be undefined. For read
operations, shifting may be terminated once the required number of bits have been acquired.
Table 36-10. MEMORY_BLOCK_ACCESS details
The overhead using block word access is 4 cycles per 32 bits of data, resulting in an 88% trans-
fer efficiency, or 2.1 MBytes per second with a 20 MHz TCK frequency.
If a very slow memory location is accessed during a SAB memory access, it could take a very
long time until the busy bit is cleared, and the SAB becomes ready for the next operation. The
CANCEL_ACCESS instruction provides a possibility to abort an ongoing transfer and report a
timeout to the user.
When the CANCEL_ACCESS instruction is selected, the current access will be terminated as
soon as possible. There are no guarantees about how long this will take, as the hardware may
not always be able to cancel the access immediately. The SAB is ready to respond to a new
command when the busy bit clears.
