Known Issues

RA0E1:
- e2 studio projects automatically reset compiler optimization to a Size setting on every generate or build operation
  - Add optimization flags (e.g. -O0) manually to 'Other optimization flags' to override the -Oz setting
- HS400x, ZMOD4xxx and OB1203 sensors cannot be used on RA0E1
- FS1015 and FS3000 sensors do not support SAU-I2C driver
Selecting 'Safely Remove Hardware and Eject Media' on Windows and eject the mass storage (PMSC), when using USBX composite device (PCDC+PMSC), the Windows Explorer for PMSC does not disappear.
PMSC may not work properly when USBX Composite Device(PCDC+PMSC) is connected to specific Linux OS (USB Host).
