The CPU and CAN module have access to this register. 15 12 11 8 7 4 3 0 DLC Reserved PRI ST 0 R/W ST The Buffer Status field contains the status information of the buffer as shown in Table 22-8. This field can be modified by the CAN module. The ST0 bits acts as a buffer busy indication. When the BUSY bit is set, any write access to the buffer is disabled with the exception of the lower byte of the CNSTAT register. The CAN module sets this bit if the buffer data is currently copied from the hidden buffer or if a message is scheduled for transmission or is currently transmitting. The CAN module always clears this bit on a status update. Table 22-8. Buffer Status Section of the CNSTAT Register ST3 ST0 ST2 ST1 BUFFER STATUS (DIR) (BUSY) 0 0 0 0 RX_NOT_ACTIVE 0 0 0 1 Reserved for RX_BUSY. (This condition indicates that software wrote RX_NOT_ACTIVE to a buffer when the data copy process is still active.) 0 0 1 0 RX_READY 0 0 1 1 RX_BUSY0 (Indicates data is being copied for the first time RX_READY → RX_BUSY0.) 0 1 0 0 RX_FULL 0 1 0 1 RX_BUSY1 (Indicates data is being copied for the second time RX_FULL → RX_BUSY1.) 0 1 1 0 RX_OVERRUN 0 1 1 1 RX_BUSY2 (Indicates data is being copied for the third or subsequent times RX_OVERRUN → RX_BUSY2.) 196 Dual CAN Interfaces Copyright © 2013, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links :CP3SP33 |
