The T89C51CC02 has a programmable 16-bit Timer (CANTIMH&CANTIML) for mes-
sage stamp and TTC.
This CAN Timer starts after the CAN controller is enabled by the ENA bit in the CANG-
CON register.
Two modes in the timer are implemented:
•
Note:
•
The CAN Timer works in a roll-over from FFFFh to 0000h which serves as a time base.
When the timer roll-over from FFFFh to 0000h, an interrupt is generated if the ETIM bit
in the interrupt enable register IEN1 is set.

Capture of this timer value in the CANTTCH & CANTTCL registers on Start
Of Frame (SOF) or End Of Frame (EOF), depending on the SYNCTTC bit in
the CANGCON register, when the network is configured in TTC by the TTC
bit in the CANGCON register.
In this mode, CAN only sends the frame once, even if an error occurs.
Capture of this timer value in the CANSTMPH & CANSTMPL registers of the
message object which received or sent the frame.
All messages can be stamps.
The stamping of a received frame occurs when the RxOk flag is set.
The stamping of a sent frame occurs when the TxOk flag is set.
