GENERAL DESCRIPTION The MSM63P180 is an M6318x series one-time-programmable ROM version product of OLMS-63K family, which employs Okis original CPU core nX-4/250. The MSM63P180 has one-time PROM as internal program memory. The MSM63188 and other mask ROM-version products have mask ROM as internal program memory. The specifications of the MSM63P180 are equal to those of the MSM63188 except for electrical characteristics, packaging, and some functions. The MSM63P180 is used for evaluating the software development of M6318x series products. FEATURES • Rich instruction set 439 instructions Transfer, rotate, increment/decrement, arithmetic operations, comparison, logic operations, mask operations, bit operations, ROM table reference, external memory transfer, stack operations, flag operations, branch, conditional branch, call/return, control. • Rich selection of addressing modes Indirect addressing of four data memory types, with current bank register, extra bank register, HL register and XY register. Data memory bank internal direct addressing mode. • Processing speed Two clocks per machine cycle, with most instructions executed in one machine cycle.
