HOST INTERFACE
-MCU needs I2C-SCL, I2C-SDA, TEST, and nRESET
DEBUGGING NEEDS
-At a minimum: UART-TX, UART-RX, and GND should be brought out to a 0.1"
header for connection to CapTIvate programmer for touch analysis
-If space allows: optional 0-ohm resistors or jumpers that would re-route TEST and
nRESET to the debugging header instead of MCU. Would allow direct programming
of MSP430 by external tool.
