VIII.2.2- ErrorStatus
The error status changeseach time an erroroccurs. When the ST75C530/540signals an errorby setting
one of the SYSERR bit, it generatesan interruptIT0. These bits can only be clearedby the host controler
using the CSE command.
The meaningof the differentbits of the SYSERRbyte is discribed below :

Meaning when set
ERR_TX
Transmitbuffer underflow. Lossof synchronisationbetweenthehost andST75C530/540 transmit
data buffer managment.
Receive buffer overflow. Loss of synchronisation between the host and ST75C530/540 receive
data buffer managment.
Vocoder buffer underflow (Decoder) or overflow (Coder). Lost of synchronisation between the
Host and ST75C530/540 VOCODER Buffer management.
