MCU Headers
The MCU headers are provided as through holes J1 to J4 for a total of 12 (6 x 2) pins. The pin headers have a
pitch of 2.54 mm and the evaluation MCU is connected to the through holes for the headers.
Table 5-5 to Table 5-8 show the pin assignments of the MCU headers.

2. P30 is connected to a 0.01-uF capacitor by default. When P39 is to be used as a port pin, short-circuit the
short-circuit pad [P30].
