Description
D1
Link2 LPC4322 BOOT0_LED indicator. Reflects the state of LPC43xx Link2 MCU
P1_1. When the boot process fails, D1 will toggle at a 1 Hz rate for 60 seconds.
After 60 seconds, the LPC4322 is reset.
DS1
K32W061/041 Power LED
DS2,
DS3
2x Red debug LEDs connected respectively to K32W061/041 PIO_0 (DS2) and
PIO_3 (DS3). LEDs are on anytime the PIO is low.
DS4
K32W061/041 Reset LED
– LED is on anytime the Target RESET is pulled low.
DS5,
DS6
Green LEDs connected respectively to UART0_Tx (DS5) and UART0_Rx (DS6).
DS8
In System Programming (ISP) LED indicator. LED is ON when SW2 button is
pressed.
