ORCC
Operation:
(CCR)
Description:
Performs bitwise logical inclusive OR between the content of memory
location M and the content of the CCR, and places the result in the CCR.
Each bit of the CCR after the operation is the logical OR of the corre-
sponding bits of M and of CCR before the operation. To set one or more
bits, set the corresponding bit of the mask equal to one. Bits correspond-
ing to zeros in the mask are not changed by the ORCC operation.
Condition Codes and Boolean Formulas:
S
⇑
Condition code bits are set if the corresponding bit was one before the
operation or if the corresponding bit in the instruction-provided mask
is one. The X interrupt mask cannot be set by any software instruction.
