2.3.1 Banks
The accessible area is divided by the 64 Kbytes. This 64-Kbyte area is called “bank.” The high-order 8 bits
of an address, which consists of 24 bits, indicate the bank. A bank is specified by the program bank
register (PG) or data bank register (DT). Each bank can be accessed efficiently by using an addressing
mode where the data bank register (DT) is used.
At each bank’s boundary, when an overflow occurs in the program counter (PC), the contents of the
program bank register (PG) is incremented by 1; when a borrow occurs in the program counter (PC), the
contents of the program bank register (PG) is decremented by 1. Accordingly, when normally programming,
it is not necessary to give consideration to bank boundaries.
2.3.2 Direct page
A 256-byte area specified by the direct page register (DPR) is called “direct page.” When setting a direct
page, set the base address (the lowest address) of an area which is to be specified as a direct page to
the direct page register (DPR). (Refer to section “2.1.8 Direct page register (DPR).”)
By using a direct page addressing mode, a direct page can be accessed with less instruction cycles.
