PowerOFF()
Purpose
Manage power consumption.
Synopsis
void PowerOFF ( IN unsigned int PowerSelect );
Parameters
PowerSelect: Input parameter
Specifies which internal devices to disable. The following possible values or any
combination (by OR’ing them) are allowed:
DISABLE_EICC
BIT14
// External Smart card.
DISABLE_VDDF
BIT13
DISABLE_UART
BIT12
DISABLE_PLL
BIT11
DISABLE_ANALOG
BIT10
DISABLE_USBXCVR
BIT9
DISABLE_USB
BIT8
DISABLE_RTC
BIT7
DISABLE_KEYPAD
BIT6
DISABLE_ICC
BIT5
DISABLE_ USBCLK
BIT4
DISABLE_LS_OSC
BIT3
// Bit 2 reserved.
CPU_HALT
BIT1
CPU_IDLE
BIT0
Return Codes
None.
Devices which are already disabled will remain disabled. Any enabled interrupt will cause an exit from
this function.
CPU_HALT has precedence over CPU_IDLE. CPU_IDLE mode stops the clock going to the CPU, all
other clocks keep running.
CPU_HALT mode can be stopped by the USB and RTC interrupts (if available), by a key press, by ICC
insertion or removal or by Reset of the 73S12xxF. In order to use these external events to wake up the
CPU, they must first be individually initialized. For example, ICC_InitUART() or KEY_Init () should be
called prior to calling PowerOFF (DISABLE_ICC) or PowerOFF (DISABLE_KEYPAD). Internally, the API
will configure INT0 to be active upon any of the events (key press, Smart Card event, etc..); thus an
application may setup its own INT0 interrupt service routine via Set_Event (eEXT0, ...) to customize its
specific needs upon waking up.
4.2.10 Analog Threshold Management Driver API – Available with all 73S12xxF Devices
This API controls the analog voltage comparison against the voltage on the ANA_IN pin. The API
includes:
ANALOG_Detect_Enable()
Purpose
Select the analog threshold level and enable the interrupt according to the polarity setting.
Synopsis
void ANALOG_Detect_Enable (
IN Unsigned char threshold_select,
IN Unsigned char acomp_pol)
