4.2.5 PLD
Cache preload.
Syntax
PLD [Rn{, FlexOffset}]
where:
Rn is the register on which the memory address is based.
FlexOffset is an optional flexible offset applied to the value in Rn .
FlexOffset can be either of the followin g:
#expr
{-}Rm{, shift}
where:
- is an optional minus sign. If - is present, the offset is subtracted
from
Rn . Otherwise, the offset is added to Rn .
expr is an expression evaluating to an integer in the range –4095 to
+4095. This is often a numeric constant.
Rm is a register containing a value to be used as the offset.
shift is an optional shift to be applied to Rm . It can be any one of:
ASR n
arithmetic shift right n bits. 1 ≤ n ≤ 32.
LSL n
logical shift left n bits. 0 ≤ n ≤ 31.
LSR n
logical shift right n bits. 1 ≤ n ≤ 32.
ROR n
rotate right n bits. 1 ≤ n ≤ 31.
RRX rotate right one bit, with extend.
This is the same offset syntax as fo r LDR and STR, words and unsigned
bytes on page4-7.
