Am I allowed to fund an HSA if I have a retirement HRA?

I am age 62. At retirement, my employer opened a "retirement HRA" (not a limited-purpose HRA) for me and funded it.  I still have the HDHP and also an HSA that was funded before retirement.  Am I allowed to fund my HSA, on my own, until age 65?  I believe not, based on page 5 of IRS pub 969 and  page 5 of IRS revenue ruling 2004-45 for Section 223, but would like other opinions.  It appears to not be entirely clear.  Thank you.
