document the bit-synth interrupt

|U21 - Pin 20 - DCLK

|3.3v - 4800Hz square wave, clocks the serial data

This is probably not directly connected to ~~U21/DCLK~~ ST7 PortF.4 which is 5V.

|Pin18 / OCMP1_A / AIN10 / ~~PF10~~PF4

|U17 appears to be a level translator between CC1050.19 and ST7.18

ST7 ADC AIN8 appears to be the only one used.

* ei0_int

** Triggered by PortA.3

** uses location 0xB2 as a shift register to output LSB first to CC1050's Data Input on PortF.4
