18. Timer1
4131J–CAN–05/06
The timer1, when used as a baud rate generator in mode 1 (16 bits counter) for low baud rates, does not generate
baud rate to UART.
Workaround
No
.
–
in Mode 1 does not generate Baud rate to UART.
Minimum code to insert in CAN interrupt routine:
__interrupt void can_int_handler(void)
{
if ((CANSIT1 & 0x40) == 0x40 )
........
........
}
{
CANPAGE = (0x0E << 4);
CANSTCH = 0x00;
CANCONCH = 0x88;
}
/* reception enable */
/* select MOb14 */
/* reset MOb14 status */
