Gosh - egg on face. Got mixed up with the PIT which usually uses a 32KHz crystal as does the RTC on the mpc860. Well, we don't have a crystal on the PIT so that (as well as the non-existant RTC) is not available!! This is what comes from trying to rely on memory alone with 1358 pages of mpc866 manual :-)) -- Robin Gilks Senior Design Engineer Phone: (+64)(3) 357 1569 Tait Electronics Fax : (+64)(3) 359 4632 PO Box 1645 Christchurch Email : robin.gilks at tait.co.nz New Zealand ** Sent via the linuxppc-embedded mail list.
