Initial value: 0:80H |
In the case of [Double direction (8255)], Specify the direction for input/output with chip number and setting value (control word) as an array with 2-elements
[Element 1]: Chip No (ChipNo)
Each LSI8255 chip corresponds to 24-bit input/output. The relationship between the number of input/output bits and the number of chips for digital device is as follows
The number of I/O bits |
The number of chips (chip number) |
24-bits I/O |
The number of chips is 1 (ChipNo 0) |
48-bits I/O |
The number of chips is 2 (ChipNo 0, 1) |
72-bits I/O |
The number of chips is 3 (ChipNo 0, 1, 2) |
96-bits I/O |
The number of chips is 4 (ChipNo 0, 1, 2, 3) |
[Element 2]: Ctrol word (CtrlWord)
The setting value is specified in Hexadecimal (80 to 9B) defined in the following table

*About the assignment of each port and IN/OUT terminals, please refer to the manual of the using board
e.g.) Chip 0 and chip 1 are set to 80, 9B
[Element 1]: 0, 1
(ChipNo)
[Element 2]: 80, 9B (CtrlWord)
There is an initial value for each input terminal setting. For example, since the initial value of [DeviceType] for selecting the type of digital device is [0 (General)], when using a digital device other than bidirectional type, there is no need to set [DeviceType] in particular.
|
For [General type] devices that are not double direction type, both the input port and output port numbers start at 0, so [Input port number 0] and [Output port number 0] exist. For double direction type devices, the port number does not change irrespective of the input/output setting state. For example, if the device is double direction type with 24 bits, 1 port has 8 bits, so there are 3 ports, the port number are 0,1,2. If the 3 ports are set as [Input, Output, Input], the port number for output is 1. Please notice that it's not 0. Please notice that it's not 0.
