5.2.3 GDU OPERATION MODE CONTROL REGISTERS

The GOPMCR Register is a control register. Therefore, the state of the GDU will not be mirrored in this register. GDUOPM bits only define the expected state of the transceiver. In addition to setting up the GDUOPM appropriately, all conditions for entering the corresponding GDU Operation modes must be fulfilled before the mode transition occurs. The GDU can also leave the expected Operation mode if the conditions to stay cannot be fulfilled. The finite state machine shown in LIN Transceiver Operating Modes will not change the GDUOPM bits.
