Description

INV

0
Invalidation of ALL caches (for CM0+ and CM4) and
ALL buffers. SW writes a '1' to clear the caches. HW
sets this field to '0' when the operation is completed.
The operation takes a maximum of three clock cycles
on the slowest of the clk_slow and clk_fast clocks. The
caches' LRU structures are also reset to their default
state.

BUFF_INV
RW1S
RW1C
0
Invalidation of ALL buffers (does not invalidate the
caches). SW writes a '1' to clear the buffers. HW sets
this field to '0' when the operation is completed. The
operation takes a maximum of three clock cycles on
the slowest of the clk_slow and clk_fast clocks.
Note: the caches only capture FLASH macro main
array data. Therefore, invalidating just the buffers
(BUFF_INV) does not invalidate captures main array
data in the caches.
