-** Abstract :\r
-** This bean "AsynchroSerial" implements an asynchronous serial\r
-** communication. The bean supports different settings of \r
-** parity, word width, stop-bit and communication speed,\r
-** user can select interrupt or polling handler.\r
-** Communication speed can be changed also in runtime.\r
-** The bean requires one on-chip asynchronous serial channel.\r
-** Settings :\r
-** Serial channel : SCI0\r
-**\r
-** Protocol\r
-** Init baud rate : 38400baud\r
-** Width : 8 bits\r
-** Stop bits : 1\r
-** Parity : none\r
-** Breaks : Disabled\r
-**\r
-** Registers\r
-** Input buffer : SCI0DRL [207]\r
-** Output buffer : SCI0DRL [207]\r
-** Control register : SCI0CR1 [202]\r
-** Mode register : SCI0CR2 [203]\r
-** Baud setting reg. : SCI0BD [200]\r
-** Special register : SCI0SR1 [204]\r

-** Method : COM0_SetBaudRateMode (bean AsynchroSerial)\r
-**\r
-** Description :\r
-** This method changes the channel communication speed (baud\r
-** rate). This method can be used only if you specify a list\r
-** of possible period settings at design time (see <Timing\r
-** dialog box> - Runtime setting - from a list of values).\r
-** Each of these settings constitutes a mode and Processor\r
-** Expert^[TM] assigns them a mode identifier. The prescaler\r
-** and compare values corresponding to each mode are\r
-** calculated at design time. You may switch modes at\r
-** runtime by referring only to a mode identifier. No\r
-** run-time calculations are performed, all the calculations\r
-** are performed at design time.\r
-** Parameters :\r
-** NAME - DESCRIPTION\r
-** Mod - Timing mode to set\r
-** Returns :\r
-** --- - Error code, possible codes:\r
-** ERR_OK - OK\r
-** ERR_SPEED - This device does not work in\r
-** the active speed mode\r
