An exception is the TBL instruction, which modifies the low byte while preserving bits 8 and 9.
2.
Each value consisted of an ASCII code in the low byte, and a colour in the high byte.
3.
These high and low bytes of the registers are sometimes referred to as Rn . 0 ( lo ) and Rn . 1 ( hi ).
4.
In this application, Port 0 outputs the low byte of the external memory address, time-multiplexed with the byte being written or read.
5.
Parameters are pushed onto the hardware stack as 16-bit integers in the order specified in the USR function in low byte, high byte order.
6.
Dot 1 corresponds to the least significant bit of the low byte of the Unicode scalar value, and dot 8 to the high bit of that byte.
7.
The Huffman tables in the header are themselves compressed : the 16 bit values in the leaves of the code tree are split into a high byte and a low byte.
8.
While the PCI bus transfers 32 bits per data phase, the initiator transmits 4 active-low byte enable signals indicating which 8-bit bytes are to be considered significant.
9.
STRUCLEV contains the current structure level ( in the high byte ) and version ( in the low byte ) of the file system; ODS-2 being structure level 2.
10.
As a timer counts down, its value can also be read directly by reading its I / O port " twice ", first for the low byte, and then for the high byte.
