56F8347 Technical Data
Preliminary
The 56F8347’s external memory interface (EMI) can operate much like the 56F80x family’s EMI,
or it can be operated in a mode similar to that used on other products in the 56800E family. Initially,
CS0 and CS1 are configured as PS and DS, in a mode compatible with earlier 56800 devices.
Eighteen address lines are required to shadow the first 192K of internal program space when
booting externally for development purposes. Therefore, the entire complement of on-chip
memory cannot be accessed using a 16-bit 56800-compatible address bus. To address this
situation, the EMI_MODE pin can be used to configure four GPIO pins as Address[19:16] upon
reset (Software reconfiguration of the highest address lines [A20-23] is required if the full address
range is to be used.)
The EMI_MODE pin also affects the reset vector address, as provided in Table 4-4. Additional
pins must be configured as address or chip select signals to access addresses at P:$10 0000 and
above.

0
Use internal P-space memory map configuration
1
Use external P-space memory map configuration – If MB = 0 at reset, changing this bit has no
effect.
