31. e when the interrupt is used an interrupt subroutine is needed and code size is increased Examples A module of an application sends once in a while one character to another device through the SCI channel If the delay between two characters is sufficient to sent one character at a time then the polling mode of the SCI the AsynchroSerial bean should be used in this case A module of an application communicates with another device i e it sends several characters at one time and receives characters from the device Thus the interrupt mode of the SCI the AsynchroSerial bean should be used in this case because when a character is received the interrupt is invoked and the underlying process of the application need not check if a character is received When a buffer for sending is used the characters are saved into the buffer and AsynchroSerial s service routine of the interrupt sends these characters without additional code of the application Note The polling mode of the bean is switched on by disabling of the Interrupt service of the bean AsynchroSerial AsynchroMaster AsynchroSlave User changes in generated code It s necessary to say at the begging of the chapter that modification of the generated code may be done only at user s own risk Generated code was hardly tested by the skilled developers and the functionality of the modified code cannot be guaranteed We strongly don t recommend modification of the generated code to the
