1) R_LPC_Create
Synopsis
Configure the MCU low power conditions.
Prototype
bool R_LPC_Create(
uint32_t data1,
// Configuration options
uint32_t data2
// Waiting times
);
Description (1/2)
Load the registers that control module or CPU operation.
[data1]
Select the required settings. If multiple selections are required, use "|" to separate each selection.
The default settings are shown in bold. Specify PDL_NO_DATA to use the defaults.
•
Software and Deep Software Standby mode output port control
