97 / 662 page  Memory Maps Overview, Rev. 4 Freescale Semiconductor 3-9 Note: The X (data) address space for all parts is actually 24 bits ($000000 - $FFFFFF) but only 21 bits are brought out externally. The chip selects can be programmed to allow data accesses above $1FFFFF. In this case the data space can be thought of as multiple 2M word pages. 3.3.1 Memory Register Summary This summary lists all accessible EOnCE Memory mapped registers in the 5685x devices, in Table 3-1. The Peripheral System Configurations are listed in Table 3-15. 3.3.1.1 Memory Mapped Registers Table 3-1 lists all of the EOnCE Memory mapped registers in the 5685x devices. Please consult the DSP56800E Reference Manual (DSP56800ERM) for complete details of the following table. Table 3-1. EOnCE Memory Map (EOnCE_BASE = $FFFF00) Address Offset Register Acronym Register Name Base + $FF OTX1/ORX1 Transmit Register Upper Word Receive Register Upper Word Base + $FE OTX/ORX Transmit Register Receive Register Base + $FD OTXRXSR Transmit /Receive Status/ Control Reg.
