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.
