Figure 14-23:
CAN 1 to 4 Interrupt Pending Registers (C1INTP to C4INTP) (2/2)
Notes: 1. x = 1 to 2 for the derivative µPD703128 (A).
2. x = 1 to 4 for the derivatives µPD703129 (A) and µPD703129 (A1).
Remarks: 1. The interrupts CxINT1 to CxINT6 are only generated when the corresponding interrupt
enable bit in the CGIE register is set.
2. The interrupt pending bits must be cleared by software in the interrupt service routine.
Caution:
In case the interrupt pending bit is not cleared by software in the interrupt service
routine, no subsequent interrupt is generated anymore.
