**     Filename  : led_section.C
**     Project   : key_scan
**     Processor : MC9S08JM60CLHE
**     Beantype  : ByteIO
**     Version   : Bean 02.055, Driver 03.15, CPU db: 3.00.033

**     Abstract  :
**         This bean "ByteIO" implements an one-byte input/output.
**         It uses one 8-bit 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 langauage and compiler).
**     Settings  :
**         Port name                   : PTE
**
**         Initial direction           : Output (direction cannot be changed)
**         Initial output value        : 0 = 000H
**         Initial pull option         : off
**
**         8-bit data register         : PTED      [$0008]
**         8-bit control register      : PTEDD     [$0009]
