ST10R172L - POWER REDUCTION MODES
13
Two different power reduction modes with different levels of power reduction can be entered
under software control.
In Idle mode the CPU is stopped, while the peripherals continue their operation. Idle mode
can be terminated by any reset or interrupt request.
In Power Down mode both the CPU and the peripherals are stopped. Power Down mode can
now be configured by software in order to be terminated only by a hardware reset or by an
external interrupt source on fast external interrupt pins.
All external bus actions are completed before Idle or Power Down mode is entered. However,
Idle or Power Down mode is not entered if READY is enabled, but has not been activated
(driven low for negative polarity, or driven high for positive polarity) during the last bus access.

The following table lists all ST10R172L SFRs in alphabetical order.
Bit-addressable SFRs are marked with the letter “b” in column “Name”. SFRs within the
Extended SFR-Space (ESFRs) are marked with the letter “E” in column “Physical Address”.
An SFR can be specified by its individual mnemonic name. Depending on the selected
addressing mode, an SFR can be accessed by its physical address (using the Data Page
Pointers), or by its short 8-bit address (without using the Data Page Pointers).
