Error in TMR_CTRL register setting in MPC8315e

Hi All,

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 19.6.6.5.1, 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 19.5.3.10.1, no where RTPE bit is mentioned in fact 16-17 bits are missing.

 

However, when i try to set bit TMR_CTRL[16] = 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.

Gourav
