**     Filename  : slave_select.H
**     Project   : spi_master
**     Processor : 56F8346
**     Beantype  : BitIO
**     Version   : Bean 02.066, Driver 01.14, CPU db: 2.87.097
**     Compiler  : Metrowerks DSP C Compiler
**     Date/Time : 2009-1-16, 8:43
**     Abstract  :
**         This bean "BitIO" implements an one-bit input/output.
**         It uses one bit/pin of a port.
**         Note: This bean is set to work in Output direction only.
**         Methods of this bean are mostly implemented as a macros
**         (if supported by target language and compiler).
**     Settings  :
**         Used pin                    :

**         Port name                   : GPIOE_Low
**
**         Bit number (in port)        : 7
**         Bit mask of the port        : 128
**
**         Initial direction           : Output (direction cannot be changed)
**         Initial output value        : 1
**         Initial pull option         : off
