** Abstract :
|
11 |
|
|
** This bean "ByteIO" implements an one-byte input/output.
|
12 |
|
|
** It uses one 8-bit port.
|
13 |
|
|
** Note: This bean is set to work in Output direction only.
|
14 |
|
|
** Methods of this bean are mostly implemented as a macros
|
15 |
|
|
** (if supported by target langauage and compiler).

|
|
** Port name : B

|
|
**
|

|
** Initial output value : 255 = 0FFH
|

|
|
** Initial pull option : off
|
