Direct Addressing Mode:
A program can branch to any address in the ROM memory space by executing
the JMPL, BRL, or CALL instruction. Each of these instructions replaces the 14 program counter bits
(PC
13
–PC
0
) with 14-bit immediate data.
Current Page Addressing Mode:
The MCU has 64 pages of ROM with 256 words per page. A program
can branch to any address in the current page by executing the BR instruction. This instruction replaces the
eight low-order bits of the program counter (PC
7
–PC
0
) with eight-bit immediate data. If the BR instruction
is on a page boundary (address 256n + 255), executing that instruction transfers the PC contents to the next
physical page, as shown in figure 94. This means that the execution of the BR instruction on a page
boundary will make the program branch to the next page.
