19.3.7 ID flag
disabling of interrupt request signals. An interrupt disable flag (ID) is assigned to the PSW.
19.3.8 Watchdog timer mode register 2 (WDTM2)
2).

This flag controls the maskable interrupt’s operating state, and stores control information regarding enabling or
Reset sets this flag to 00000020H.
This register can be read or written in 8-bit units (for details, see CHAPTER 11 FUNCTIONS OF WATCHDOG TIMER
Reset sets this register to 67H.
Note Interrupt disable flag (ID) function
After reset:
PSW
This bit is set to 1 by the DI instruction and cleared to 0 by the EI instruction. Its value is also modified by
the RETI instruction or LDSR instruction when referencing the PSW.
Non-maskable interrupt request signals and exceptions are acknowledged regardless of this flag. When
a maskable interrupt request signal is acknowledged, the ID flag is automatically set to 1 by hardware.
The interrupt request signal generated during the acknowledgment disabled period (ID flag = 1) is
acknowledged when the xxICn.xxIFn bit is set to 1, and the ID flag is cleared to 0.
