ST92163 - GENERAL DESCRIPTION

1.5 ST92163 REGISTER MAP

Table 6 contains the map of the group F peripheral

pages.

The common registers used by each peripheral

are listed in Table 5.

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 initialized.

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.

These register groups (16 registers per group)

are potentially reserved for USB DMA.

The amount of reserved registers depends on

the number of endpoints used in the program.

(8 registers are used per endpoint).
