ually as S-bit registers, or as 6-bit register pairs. Also included are two sets of accumulator and flag registers.
Through a group of exchange instructions the programmer has access to either set of main or alternate registers. The alternate register permits foreground/background mode of operation, or may be u~ed fv( fast interrupt response. A l6-bit stack pointer is also included in each processor, simplifying implementation of multiple level interrupts, permitting unlimited subroutine nesting, and simplifying many types of data handling.
The two 16-bit index registers simplify implementatio... |
