Example 1 :Starting STOP mode from NORMAL mode by testing a port P20.

Note 3: Bits 3, 1 and 0 in SYSCR2 are always read as undefined value.
Note 4: Do not set IDLE and TGHALT to “1” simultaneously.
Note 5: Because returning from IDLE0/SLEEP0 to NORMAL1/SLOW1 is executed by the asynchronous internal clock, the period
Note 6: When IDLE1/2 or SLEEP1/2 mode is released, IDLE is automatically cleared to “0”.
Note 7: When IDLE0 or SLEEP0 mode is released, TGHALT is automatically cleared to “0”.
Note 8: Before setting TGHALT to “1”, be sure to stop peripherals. If peripherals are not stopped, the interrupt latch of peripherals

level-sensitive release mode, it is necessary for the program to first confirm that the STOP pin input is
low and the STOP5 to STOP2 inputs are high. The following two methods can be used for confirmation.
1. Oscillations are turned off, and all internal operations are halted.
2. The data memory, registers, the program status word and port output latches are all held in the

4. The program counter holds the address 2 ahead of the instruction (e.g., [SET (SYSCR1).7]) which
