How to inactive Mailbox of FlexCAN?

[SONGTAOSI]

Hi，

In my project, I want to inactivate MB1(transmission mailbox). According to the 53.5.7.2 of the reference manual, I should update the CODE field to INACTIVE (0b1000) ,and MCR[AEN] = 0.

What bothers me is that how can I write 0b1000 to Code field? No register can be operation.My device is S32K148,and S32 Design Studio for S32 Platform 3.4. Looking forward to your reply！
