Version:V1.1
The chip has built-in 1M bytes internal ROM including 512K bytes program ROM and 512K bytes data
ROM. In addition, address and data buses are provided to access External ROM. The MCU can access up
to 4 MB Program ROM and up to 16 MB Data space through external buses. The SEG[79..72],
SEG[71..44] pads are used as either data and address buses for external ROM or LCD segment driver
pads depending on the mask option MO_EXMEM. When the external ROM mask option is selected, the
MCU will retrieve the instructions and data from external ROM through the address and data buses and
the SEG[79..44] will not be LCD segment signals.
The bit 14 ~ 15 bit of 16-bit logical program address can be mapped to any one of 256 pages through
mapping registers PSA1, PSA2, PSA3. As logical page 0 can not be moved and is always physical page 0,
the PSA1 ~ PSA3 contain the physical page addresses of logical pages 1 ~ 3.
