If the mailbox ID's purpose, for example
set the nth mailbox, When I increase the ID value, for example, if I double it, does the mailbox covers double?

For example, I define a macro in my code, #define TX_MAILBOX_IDX 1 -> that means selected address offset?
If that is true, my address offset is 0090? or 0090 - 0080?
so,
I ask this because, in my code sample, I was changing the message buffer index value(RX or TX, RX and TX) anything changed. I use an 8-byte payload.
I didn't understand your question. If you have questions about the details of FlexCAN, you can read our data sheet, and we also have a complete demo for customer reference,
for example:

Actually, I cannot understand, If I increase the mailbox index, does my message buffer's memory area increase?
