pub type MASK_W<'a, const O: u8> = FieldWriter<'a, u32, MASTER_SPEC, u8, u8, 5, O>;Expand description
Field MASK writer - This value determines the maximum size of the trace buffer in SRAM. It specifies the most-significant bit of the POSITION.POINTER field that can be updated by automatic increment. If the trace tries to advance past this power of two, the POSITION.WRAP bit is set to 1, the POSITION.POINTER[MASK:0]
bits are set to zero, and the POSITION.POINTER[AWIDTH-4:MASK+1]
bits remain unchanged. This field causes the trace packet information to be stored in a circular buffer of size 2(MASK+4) bytes, that can be positioned in memory at multiples of this size. Valid values of this field are zero to AWIDTH-4. Values greater than the maximum have the same effect as the maximum.
