The Timer function is the functional entity, which provides RCAN-TL1 with support for

transmitting messages at a specific time frame and recording the result.

The Timer is a 16-bit free running up counter which can be controlled by the CPU. It provides

one 16-bit Compare Match Register to compare with Local Time and two 16-bit ones to

compare with Cycle Time. The Compare Match Registers can generate interrupt signals and

clear the Counter.

The clock period of this Timer offers a wide selection derived from the system clock or can be

programmed to be incremented with one nominal bit timing of CAN Bus.

Contains registers such as TCNTR, TTCR0, CMAX_TEW, RETROFF, TSR, CCR, CYCTR,

RFMK, TCMR0, TCMR1, TCMR2 and TTTSEL.

This block conforms to the requirements for a CAN Bus Data Link Controller which is

specified in Ref. [2, 4]. It fulfils all the functions of a standard DLC as specified by the OSI 7

Layer Reference model. This functional entity also provides the registers and the logic which

are specific to a given CAN bus, which includes the Receive Error Counter, Transmit Error

Counter, the Bit Configuration Registers and various useful Test Modes. This block also

contains functional entities to hold the data received and the data to be transmitted for the

CAN Data Link Controller.
