+ * Pin / Name / Function
+ *   1    PA6   (none) (PWM1B) (reserved for DD drivers)
+ *   2    PA5   R: red aux LED (PWM0B)
+ *   3    PA4   G: green aux LED
+ *   4    PA3   B: blue aux LED
+ *   5    PA2   L: button LED

+ *  11    PC4   (none)
+ *  12    PC3   RESET
+ *  13    PC2   (none)
+ *  14    PC1   SCK
+ *  15    PC0   boost PMIC enable (PWM0A not used)
+ *  16    PB3   main LED PWM (PWM1A)
+ *  17    PB2   MISO / e-switch (PCINT10)
+ *  18    PB1   MOSI / battery voltage (ADC6)
+ *  19    PB0   Opamp power
+ *  20    PA7   (none)  (PCINT7)
+ *      ADC12   thermal sensor
+ *
+ * Main LED power uses one pin to turn the Opamp on/off,
+ * and one pin to control Opamp power level.
+ * Linear brightness control uses the power level pin, with dynamic PWM.
+ * The on/off pin is only used to turn the main LED on and off,
+ * not to change brightness.
