3.2 S Registers
A number of terminal adapter settings have to be done by means of S registers.
A number of registers have one meaning (function). Other registers have several functions and are called bitmapped
registers. In these registers, settings or commands are done at bit level.
The following section explains what bitmapped means.
A detailed description of the commands including the accompanying parameters can be found from section 3.4 onward.
3.2.1 Bitmapped S registers
In bitmapped S registers, a function is switched on or off per bit. '1' means the bit is on or ‘set’ ; '0' means the bit is off or
‘reset’..
These bits from the binary system represent a decimal value. Bit 7=128, 6=64, 5=32, 4=16, 3=8, 2=4, 1=2 en 0=1. If you add
the decimal value of the bits that are ‘1’ , the result is the value that has to be set in the register.
