MEMC – Clear bit in memory
Architecture revision:
Architecture revision1 and higher.
Description
Performs a read-modify-write operation to clear an arbitrary bit in memory. The word to modify is pointed to
by a signed 17-bit address. This allows the instruction to address the upper 64KB and lower 64KB of mem-
ory. This instruction is part of the optional RMW instruction set.
