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.
