176 / 407 page  SYNC External Reset or Enable CR16CAN 11 consecutive 'recessive" bits received (TEC OR REC) > 95 128 occurrences of 11 consecutive 'recessive" bits TEC > 255 ERROR ACTIVE ERROR WARNING ERROR PASSIVE (TEC AND REC) < 96 (TEC OR REC) > 127 (TEC AND REC) < 128 BUS OFF DS027 CP3SP33 SNOSCW5 – MAY 2013 www.ti.com 22.2.4.3 Form Error A form error is detected, if a fixed frame bit (e.g., CRC delimiter, ACK delimiter) does not have the specified value. For a receiver, a “dominant” bit during the last bit of End of Frame does not constitute a frame error. 22.2.4.4 Bit CRC Error A CRC error is detected if the remainder from the CRC calculation of a received CRC polynomial is non- zero. 22.2.4.5 Acknowledgment Error An acknowledgment error is detected whenever a transmitting node does not get an acknowledgment from any other node (i.e., when the transmitter does not receive a “dominant” bit during the ACK frame). 22.2.4.6 Error States The device can be in one of five states with respect to error handling (see Figure 22-10). Figure 22-10. Bus States 22.2.4.7 Synchronize Once a CAN module is enabled, it waits for 11 consecutive recessive bits to synchronize with the bus. After that, a CAN module becomes error active and can participate in the bus communication. This state must also be entered after waking-up the device using the Multi-Input Wake-Up feature. See Section 22.11. 22.2.4.8 Error Active An error active unit can participate in bus communication and may send an active (“dominant”) error flag. 22.2.4.9 Error Warning The Error Warning state is a sub-state of Error Active to indicate a heavily disturbed bus. A CAN module behaves as in Error Active mode. The device is reset into the Error Active mode if the value of both counters is less than 96. 176 Dual CAN Interfaces Copyright © 2013, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links :CP3SP33 |
