< Compile Options / Microcontroller Options >
The default for this option is determined based on the environment variable ISA_RX.
When neither the -nofpu nor -fpu option has been selected, specifying this option automatically selects the -fpu option. |
Omitting this option when neither the -cpu option nor one of the environment variables (CPU_RX or ISA_RX) is specified will lead to an error. |
