Section 9 Power-Down Modes
9.9
9.9.1
After a power-on reset, the current consumption may exceed the maximum value for sleep mode
or standby mode during the period until one or more of the arithmetic operation or floating-point
operation instructions listed below is executed.
1. Arithmetic operation instructions
2. Floating-point operation instructions
Workaround: After a power-on reset, execute one or more of the above instructions before
transitioning to sleep mode or standby mode.
Example: To reduce the effect on FPSCR, arrange the following two instructions starting at
H'A0000000.
