■ Applicable version
v.1.0.0, v.1.1.0

■API affected by defect
Random()
Random() is a function that generates a 32-bit random number and returns it as a return value.

■ Contents and occurrence conditions
There was an issue where Random() only returned a 15-bit random number.

■ Workaround
none

■ Permanent measures
Fixed in v.1.2.0.

■ Corresponding version
v.1.0.0 and v.1.1.0

■ Contents and Occurrence conditions
The attachInterrupt function is originally a function that sets the specified interrupt pin as an input port and defines an interrupt handler. However, there was a problem in which all interrupt pins were set to input ports in the attachInterrupt function. Therefore, if a specific terminal is set as output before calling the attachInterrupt function, that terminal will be overwritten as input.
The pins to be initialized are as follows
P04, P41, P137

■ Workaround
1. Set the attachInterrupt() function at the beginning of the setup function.
2. After setting 1, Set the next output terminal with pinMode

■ Permanent measures
Fixed in v.1.2.0.
