45 / 84 page  Starting at the adddress $08 the status area have the following format : Add.

When the ST75C530/540 signals an error by setting one of the SYSERR bit, it generates an interrupt IT0. These bits can only be cleared by the host controler using the CSE command. The meaning of the different bits of the SYSERR byte is discribed below : SYSERR Field Pos. Meaning when set ERR_TX 0 Transmit buffer underflow. Loss of synchronisation between the host and ST75C530/540 transmit data buffer managment. ERR_RX 1 Receive buffer overflow. Loss of synchronisation between the host and ST75C530/540 receive data buffer managment. ERR_VOCO 2 Vocoder buffer underflow (Decoder) or overflow (Coder). Lost of synchronisation between the Host and ST75C530/540 VOCODER Buffer management. ERR_IOCD 3 Incorrect command ERR_IPRM 4 Incorrect parameter for the command ERR_RTK 7 Real time kernel error. ST75C530/540 not able to perform all its tasks within the baud period (transmit or receive samples lost). VIII - STATUS DESCRIPTION (continued) ST75C530 - ST75C540 45/84 |
