6.2 CPU Registers
6.2.1
General-purpose registers
Sixteen 8-bit general-purpose registers are available. Two 8-bit registers can be also used in pairs as a 16-bit
register. Of the 16-bit registers, four can be used in combination with an 8-bit register for address expansion as 24-
bit address specification registers.
Eight banks of these registers are available which can be selected by using software or the context switching
function.
The general-purpose registers except V, U, T, and W registers for address expansion are mapped to the internal
RAM.

Caution Registers R4, R5, R6, R7, RP2, and RP3 can be used as X, A, C, B, AX, and BC registers,
respectively, by setting the RSS bit of the PSW to 1. However, use this function only for
recycling the program of the 78K/III Series.
