EOnCE Memory Map
Control registers of the EOnCE are located at the top of data memory space. These locations are fixed by the 56800E core. These
registers can also be accessed through the JTAG port if flash security is not set. Table 13 lists all EOnCE registers necessary to
access or control the EOnCE.
