Read-Modify-Writ
e Instructions
These instructions read a memory location or a register, modify its
contents, and write the modified value back to the memory location or to
the register.
NOTE:
Do not use read-modify-write operations on write-only registers.

ASR
Bit Clear
BCLR(1)
1. Unlike other read-modify-write instructions, BCLR and
BSET use only direct addressing.
