 y is the decimal representation for the binary number CRm.
In Table 13.28,
mode> refer to the rDTR and
MCR p14,0,<Rd>,c0,c5,0 and
p14,c5,<addressing mode> refer to the wDTR. See CP14 c5, Data Transfer
Registers (DTR) for more details.
MRC p14,0,R15,c0,c1,0 instruction sets
the CPSR flags as follows:
N flag = DSCR. This is an Unpredictable value.
Z flag = DSCR. This is the value of the rDTRfull flag.
C flag = DSCR. This is the value of the wDTRfull flag.
V flag = DSCR. This is an Unpredictable value.
Instructions that follow the MRC instruction can be conditioned to these CPSR flags.
