WebThis register includes DPH (high byte) & a DPL (low byte) which is mainly used to hold a 16-bit address. So, it can be used as a base register within not direct jumps, lookup table instructions & external data transfer. Program counter or PC is a 16-bit register used to store the next instruction’s address to be performed WebThis is required to allow 20 bit data pointers and accessing (constant) data above 64k. However, it makes the code bigger and slower, requiring two 16 bit writes on each register save (and restore). There are a few MSPs with RAM above 64k. In this case, of course variables can be placed in RAM too and are read/write then.

The MIT Whirlwind (c. 1951) was quite possibly the first-ever 16-bit computer. It was an unusual word size for the era; most systems used six-bit character code and used a word length of some multiple of 6-bits. This changed with the effort to introduce ASCII, which used a 7-bit code and naturally led to the use of an 8-bit multiple which could store a single ASCII character or two binary coded decimal digits.
