Note 1: Do not set the IMF and the interrupt enable flag (EF15 to EF4) to "1" at the same time.
Note 2: In the main program, before manipulating the interrupt enable flag (EF), be sure to clear the master enable flag (IMF) to
Note 3: When a read instruction is executed on EIRL, bits 3 to 1 are read as "0". Other unused bits are read as "0".

"0" (Disable interrupt by DI instruction). Then set the IMF to "1" as required after operating the EF (Enable interrupt by EI
instruction)
In the interrupt service routine, the IMF becomes "0" automatically and need not be cleared to "0" normally. However, if
using multiple interrupt in the interrupt service routine, manipulate the EF before setting the IMF to "1".
