When the execution condition goes from OFF
to ON, DIFU(013) turns R ON. When
DIFU(013) is reached in the next cycle, R is
turned OFF.
• UP(521) can be used to execute an instruction for just one cycle when the execution condition goes
from OFF → ON.
• DIFU(013) has immediate refreshing variation (!DIFU(013)). When a CPU Unit built-in output bit has
been specified for R in this instruction, any changes to R will be refreshed when the instruction is exe-
cuted and reflected immediately in the output bit.
