LED Behavior 1 - 81h
Bits 7 - 6 - LED4_CTL[1:0] - Determines the behavior of LED4 / GPIO4 when configured to operate
as an LED output
Bits 5 - 4 - LED3_CTL[1:0] - Determines the behavior of LED3 / GPIO3 when configured to operate
as an LED output
Bits 3 - 2 - LED2_CTL[1:0] - Determines the behavior of LED2 / GPIO2 when configured to operate
as an LED output
Bits 1 - 0 - LED1_CTL[1:0] - Determines the behavior of LED1 / GPIO1 when configured to operate
as an LED output
LED Behavior 2 - 82h
Bits 7 - 6 - LED8_CTL[1:0] - Determines the behavior of LED8 / GPIO8 when configured to operate
as an LED output
Bits 5 - 4 - LED7_CTL[1:0] - Determines the behavior of LED7 / GPIO7 when configured to operate
as an LED output
Bits 3 - 2 - LED6_CTL[1:0] - Determines the behavior of LED6 / GPIO6 when configured to operate
as an LED output
Bits 1 - 0 - LED5_CTL[1:0] - Determines the behavior of LED5 / GPIO5 when configured to operate
as an LED output
LED Behavior 3 - 83h
Bits 7 - 6 - LED11_ALT[1:0] - Determines the behavior of LED 11 when the PWR_LED bit is set and
either the SLEEP or DSLEEP bits are set (see Section 5.1).
Bits 5 - 4 - LED11_CTL[1:0] - Determines the behavior of LED11 when the PWR_LED bit is set and
both the SLEEP and DSLEEP bits are not set (see Section 5.1).
Bits 3 - 2 - LED10_CTL[1:0] - Determines the behavior of LED10.
Bits 1 - 0 - LED9_CTL[1:0] - Determines the behavior of LED9.
APPLICATION NOTE: When driving the LED / GPIOx output as a GPO, the LEDx_CTL[1:0] bits should be set to
00b.
