The RAM page index register allows accessing up to (1M minus 2K) bytes of RAM in the global memory
map by using the eight page index bits to page 4 Kbyte blocks into the RAM page window located in the
CPU local memory map from address $1000 to address $1FFF (see

Internal means resources inside the MCU are read/written.
Internal Flash means Flash resources inside the MCU are read/written.
Emulation memory means resources inside the emulator are read/written (PRU registers, flash
replacement, RAM, EEPROM and register space are always considered internal).
External application means resources residing outside the MCU are read/written.
The external access stretch mechanism is part of the EBI module (refer to EBI Block Guide for details).
