41 / 175 page  High-Speed Microcontroller User’s Guide 41 of 175 ROM Size Select (ROMSIZE) 7 6 5 4 3 2 1 0 SFR C2h - - - - - RS2 RS1 RS0 RT-1 RT-0 RT-1 R=Unrestricted Read, W=Unrestricted Write, -n=Value after Reset Bits 7-3 These bits are reserved. Read data is indeterminate. ROMSIZE.2-0 Bits 2-0 ROM Size Select 2-0. This register is used to select the maximum on-chip decoded address for ROM. Care must be taken that the memory location of the current program counter will be valid both before and after modification. These bits can only be modified using a timed access procedure. The EA pin will override the function of these bits when asserted, forcing the device to access external program memory only. Configuring this register to a setting that exceeds the maximum amount of internal memory may corrupt device operation. These bits will default on reset to the maximum amount of internal program memory (i.e., 16K for DS87C520).
