 *   2    PA5   R: red aux LED (PWM0B)

 *  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.
