938 config BFIN_INS_LOWOVERHEAD
939 bool "ins[bwl] low overhead, higher interrupt latency"
943 Reads on the Blackfin are speculative. In Blackfin terms, this means
944 they can be interrupted at any time (even after they have been issued
945 on to the external bus), and re-issued after the interrupt occurs.
946 For memory - this is not a big deal, since memory does not change if
949 If a FIFO is sitting on the end of the read, it will see two reads,
950 when the core only sees one since the FIFO receives both the read
951 which is cancelled (and not delivered to the core) and the one which
952 is re-issued (which is delivered to the core).
954 To solve this, interrupts are turned off before reads occur to
955 I/O space. This option controls which the overhead/latency of
956 controlling interrupts during this time
957 "n" turns interrupts off every read
958 (higher overhead, but lower interrupt latency)
959 "y" turns interrupts off every loop
960 (low overhead, but longer interrupt latency)
962 default behavior is to leave this set to on (type "Y"). If you are experiencing
963 interrupt latency issues, it is safe and OK to turn this off.

1264 The PLL and system clock (SCLK) continue to operate at a very low
1265 frequency of about 3.3 MHz. To preserve data integrity in the SDRAM,
1266 the SDRAM is put into Self Refresh Mode. Typically an external event
1267 such as GPIO interrupt or RTC activity wakes up the processor.
1268 Various Peripherals such as UART, SPORT, PPI may not function as
1269 normal during Sleep Deeper, due to the reduced SCLK frequency.
