4.2.9 Power Management API – Available with all 73S12xxF Devices

The Power Management API configures the active devices, thereby managing the power consumption of

the 73S12xxF. The API includes:

• PowerON() (page 52)

• PowerOFF() (page 53)

PowerON()

Purpose Manage power consumption.

Synopsis Void PowerON ( IN unsigned int PowerSelect );

Parameters PowerSelect: Input parameter

Specifies which internal devices to enable. The following possible values (defined in

API_12.h) or any combination (by OR’ing them) are allowed:

ENABLE_EICC BIT14 // External Smart card.

ENABLE_VDDF BIT13 // VDD fault detection

ENABLE_UART BIT12 // Serial

ENABLE_PLL BIT11

ENABLE_ANALOG BIT10

ENABLE_USBXCVR BIT9 //USB Transceiver, Unavailable with 73S1205F

ENABLE_USB BIT8 //D+, Unavailable with 73S1205F

ENABLE_RTC BIT7 // Unavailable with 73S1205F

ENABLE_KEYPAD BIT6

ENABLE_ICC BIT5 // Smart card.

ENABLE_USBCLK BIT4 //USB Clock, Unavailable with 73S1205F

ENABLE_LS_OSC BIT3 //Low speed OSC-32kHz, Unavailable with

73S1205F

Bits 2, 1 and 0 are reserved for MCount value. Devices which are already enabled

will remain enabled.

Return Codes None.
