TMS320F280049: CLB1 and CLB2 in SOFTPRES17 register mus be R/W-0h ( in SPRUI33C)

Hi Experts,

There is  the register bit field description in 3.14.11.19 SOFTPRES17 Register on page 348 in the TRM for F28004x( SPRUI33C ).

As you can see bit fields for CLB1 and CLB2 are R-0h.  ( It must be a typo. )
However, CLB3 and CLB4 are R/W-0h.

I believe that CLB1 and CLB2 are R/W-0h like the description in the TRM for F28388x (SPRUII0B ).
Could you please clarify the two bits?

Thank you for your kind check.
Best regards,
Hitoshi
