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

1265 The PLL and system clock (SCLK) continue to operate at a very low
1266 frequency of about 3.3 MHz. To preserve data integrity in the SDRAM,
1267 the SDRAM is put into Self Refresh Mode. Typically an external event
1268 such as GPIO interrupt or RTC activity wakes up the processor.
1269 Various Peripherals such as UART, SPORT, PPI may not function as
1270 normal during Sleep Deeper, due to the reduced SCLK frequency.
