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

1267 The PLL and system clock (SCLK) continue to operate at a very low
1268 frequency of about 3.3 MHz. To preserve data integrity in the SDRAM,
1269 the SDRAM is put into Self Refresh Mode. Typically an external event
1270 such as GPIO interrupt or RTC activity wakes up the processor.
1271 Various Peripherals such as UART, SPORT, PPI may not function as
1272 normal during Sleep Deeper, due to the reduced SCLK frequency.
