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() (page 53)

• ANALOG_Detect_Disable() (page 54)

• ANALOG _Compare() (page 54)

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)
