I have an interrupt which is updating data, which can also be read using other functions.
I need to be able to read data knowing that it is not being updated mid way through the read.
On the S12 I would do this:
disable all interrupts using the DisableInterrupts function which would update the I bit in the CCR register.
perform the action
enable all interrupts using the EnableInterrupts function
What is the equivalent for the MPC5604?
