LED_Config ()

Purpose Configure the LED interface (all pins).

Synopsis Void LED_Config ( IN Bbool PU_Enable, IN enum LED_CURRENT LC );

Parameters PU_Enable: Input parameter

Boolean value specifies enable (TRUE) or disable (FALSE) pull-up.

LC: Input parameter

Enum type indicating the output current level for the LEDs (when turned on). The

following values are available:

LED_OFF: turn off LED (0 mA).

LED_DIM: turn LED on at dim level (2 mA).

LED_NORMAL: turn LED on at normal level (4 mA).

LED_BRIGHT: turn LED on at brightest level (10 mA).

Return Codes None.

LED_Write ()

Purpose Turn LED on/off. If turned on, the brightness control is possible at one of three

levels: Dim, Normal, Bright as specified in LED_Config().

Synopsis Void LCD_ Write ( IN unsigned char LED_Pin, IN unsigned char Value );

Parameters LED_Pin : Input parameter

Selected LED(s) to be turned on, where bit[n] = 1 indicates LED[n] to be written.

Value: Input parameter

Value to be written to selected LED. Bit[n] is the value to be written to LED[n] if

LED[n] is selected to be written to.

Return Codes None.

LED_Read ()

Purpose Read current state of the LED data.

Synopsis Void LCD_Read ( OUT unsigned char LEDValue );

Parameters LEDvalue: Output parameter

Bit[0] indicates the current state of LED0.

Bit[1] indicates the current state of LED1.

Bit[2] indicates the current state of LED2 – Not available in 73S1205F.

Bit[3] indicates the current state of LED3 – Not available in 73S1205F.

Bit[4] indicates the state of the pull-up (1=enable).

Bit[5,6] indicate the output current level where:

00 = OFF

01 = DIM

10 = NORMAL

11 = BRIGHT

Return Codes None.
