ST90158 - REGISTER AND MEMORY MAP
3.4 ST90158/135 REGISTER MAP
The following pages contain a list of ST90158/135
registers, grouped by peripheral or function.
Be very careful to correctly program both:
– The set of registers dedicated to a particular
function or peripheral.
– Registers common to other functions.
– In particular, double-check that any registers
with “undefined” reset values have been correct-
ly initialised.
Warning: Note that in the EIVR and each IVR reg-
ister, all bits are significant. Take care when defin-
ing base vector addresses that entries in the Inter-
rupt Vector table do not overlap.
