The OR LOAD instruction can be used repeatedly. In programming method
(2) above, however, the number of OR LOAD instructions becomes one less
than the number of LOAD and LOAD NOT instructions before that.
In method (2), make sure that the total number of LOAD and LOAD NOT
instructions before OR LOAD is not more than eight. To use nine or more, pro-
gram using method (1). If there are nine or more with method (2), then a pro-
gram error will occur during the program check by the Peripheral Device.
