28.5.4.4 LDR, PC-relative
LDR, LDRB, U, LDRSB and LDRSH load the register specified by Rt with either a word,
zero extended byte, zero extended halfword, sign extended byte or sign extended
halfword value from memory.
STR, STRB and STRH store the word, least-significant byte or lower halfword contained
in the single register specified by Rt into memory.
The memory address to load from or store to is the sum of the values in the registers
specified by Rn and Rm.
In these instructions:
These instructions do not change the flags.
Load register (literal) from memory.
LDR Rt, label
where:
Loads the register specified by Rt from the word in memory specified by label.
In these instructions, label must be within 1020 bytes of the current PC and word aligned.
These instructions do not change the flags.

Rt is the register to load.
label is a PC-relative expression. See
Rt, Rn, and Rm must only specify R0-R7.
the computed memory address must be divisible by the number of bytes in the load or
store, see
