Precautions when using the RL78 Arduino Library

Unable to upload during serial communication on Linux

Print.h cannot be included

All interrupt pins become input ports when attachInterrupt() is executed

Executing analogReference() sets a specific port to analog settings

The return value of the Random() is only 15 bits

LED doesn't blink when using the sample sketch "blink"

Not change the input settings when analogRead() is called

PWM waveform is not output when analogWrite() is called

Some pins cannot be used as transmit pins in SoftwareSerial

Calling pinMode() does not allow for the digital output setting

Calling digitalRead() does not read the input value

SCL and SDA cannot be used in pinMode() and digitalRead()

Verify/Compile with Trigonometric functions library will result in an error

Including certain header files causes build errors due to duplicate functions
