I'm trying to enable 1588 HW time stamping in my custom board based on MPC8315eRDB.
As per ref. manual[Rev-2.0], It supports. And i can see 1588 related registers also.
As per theory section 220.127.116.11.1, TMR_CTRL[RTPE] = 1 then only HW time stamping will be written to TxPAL. But when i check register definition of TMR_CTRL in section 18.104.22.168.1, no where RTPE bit is mentioned in fact 16-17 bits are missing.
However, when i try to set bit TMR_CTRL = 1, changes not reflecting. It's always "0".
Pls some one help me here how to set TMR_CTRL[RTPE] bit in MPC8315e.
Thanks in advance.
