• Manufacturer Part Number: T89C51CC02
• Description: 8-Bit MCU
• Manufacturer: Atmel

To enable a transmission interrupt:
To enable a reception interrupt:
To enable an interrupt on message object error:
To enable an interrupt on general error:
To enable an interrupt on Buffer-full condition:
To enable an interrupt when Timer overruns:
When an interrupt occurs, the corresponding message object bit is set in the SIT register.
To acknowledge an interrupt, the corresponding CANSTCH bits (RXOK, TXOK,...) or CANGIT bits (OVRTIM,
OVRBUF,...), must be cleared by the software application.
When the CAN node is in transmission and detects a Form Error in its frame, a bit Error will also be raised.
Consequently, two consecutive interrupts can occur, both due to the same error.
When a message object error occur and set in CANSTCH register, no general error are setting in CANGIE register.
