Variables declared without a memory type specifier are stored in the default or implicit memory area. Function arguments and automatic variables that cannot be allocated to MCU registers are also stored in the default memory area.
The default memory type is determined by the memory model selected. For global variables, the HOLD directive allows you to specify size limits and alternative implicit memory spaces.
