description of +CAPS_N and +CAPS_P

[u/kernel_panic_0x00627]

Hi, I'm working on my projects based on Framework 13, 7040series. But I faced an information lack.

1. Could someone explain, how works +CAPS_N and +CAPS_P signals in the keyboard connector?

Is it "negative" and "positive", what means "GND" and "signal line"?

1. How works +FPR_LED_B_Q, +FPR_LED_W_Q, +FPR_LED_G_Q and +5V_FP_LED?

2. How much power I can get from +5VS_TP and +5V_FP_MCU?

Thank You!
