Field : FILTERS_0_WINDOWSIZE

Register WindowSize contains the encoded address mask used to filter packets. The effective Mask value is equal to ~(2max(WindowSize, packet.Len) - 1). A packet is a candidate when packet.Addr & Mask = AddrBase & Mask. This allows filteringof packets having an intersection with the AddrBase/WindowSize burst aligned region, even if the region is smaller than the packet.

Data Structure Documentation

struct ALT_NOC_MPU_PRB_MPU_MAIN_FLTS_0_WINDOWSIZE_s

WARNING: The C register and register group struct declarations are provided for convenience and illustrative purposes. They should, however, be used with caution as the C language standard provides no guarantees about the alignment or atomicity of device memory accesses. The recommended practice for writing hardware drivers is to use the SoCAL access macros and alt_read_word() and alt_write_word() functions.
