selected. In addition, the active-low emulation chip select signal, ECS, will likewise function based upon
the assigned memory allocation. In the cases of 48K byte and 64K byte allocated physical FLASH/ROM
space, the operation of the ECS signal will additionally depend upon the state of the ROMHM bit (see
Section 19.3.2.4, “Miscellaneous System Control Register

allocated memory configuration. Again, this signal information is only available externally when the EMK
bit is set and the system is in an expanded mode.
