34.2.9.3.4 Condition flags
34.2.9.3.5 Example
Other restrictions when using an IT block are:
Remark: Your assembler might place extra restrictions on the use of IT blocks, such as
prohibiting the use of assembler directives within them.
This instruction does not change the flags.

CPSID and CPSIE.
a branch or any instruction that modifies the PC must either be outside an IT block or
must be the last instruction inside the IT block. These are:
– ADD PC, PC, Rm
– MOV PC, Rm
– B, BL, BX, BLX
– any LDM, LDR, or POP instruction that writes to the PC
– TBB and TBH
do not branch to any instruction inside an IT block, except when returning from an
exception handler
all conditional instructions except Bcond must be inside an IT block. Bcond can be
either outside or inside an IT block but has a larger branch range if it is inside one
each instruction inside the IT block must specify a condition code suffix that is either
the same or logical inverse as for the other instructions in the block.
