ROM Addressing Modes
Direct Addressing Mode:
A program can branch to any address in ROM memory space by executing the
JMPL, BRL, or CALL instruction.
Current Page Addressing Mode:
A program can branch to any address in the current page (256 words
per page) by executing the BR instruction.
Zero-Page Addressing Mode:
A program can branch to any subroutine located in the zero-page
subroutine area ($0000–$003F) by executing the CAL instruction.
Table Data Addressing Mode:
A program can branch to an address determined by the contents of 4-bit
immediate data, the accumulator, and the B register by executing the TBR instruction.
