Since the PC does not increment during execution of GETI instruction, it continues processing
with the address following GETI instruction.
If an instruction preceding the GETI instruction has the skip function, the GETI instruction is
skipped as is the case with all other 1-byte instructions. If the instruction referred to by the GETI
instruction has the skip function, an instruction following the GETI instruction is skipped.
When instructions having stack effects are referred to by the GETI instruction, the following
operations are carried out:
If an instruction preceding GETI instruction also has the stack effects of the same group, the
execution of GETI instruction eliminates the stack effects and the instructions referred to are not
skipped.
If an instruction following GETI instruction also has the stack effects of the same group, the stack
effects derived from the instructions referred to are valid and the following instruction is skipped.

Bit manipulation instruction
In addition to normal bit manipulation instructions (set and clear instructions), the bit test instruction,
bit transfer instruction and bit Boolean instructions (AND, OR, XOR) are available for the
μ
PD75236.
Manipulation bits are specified by bit manipulation addressing.
Three types of available addressing operations and bits manipulated by each addressing are shown
below.
