Identification Register Block
All new derivatives of Infineons C16x microcontroller family provide a set of min. four
identification registers (expandable to eight). These registers offer information on the
chip manufacturer, the chip type and its memory properties.
Identification registers in the ID Block:
20.3
The XBUS peripherals can be separately selected for being visible to the user by means
of corresponding selection bits in the XPERCON register. If not selected and therefore
not enabled (not activated with XPERCON bit), the peripheral’s address space including
SFR addresses and port pins are not occupied by the peripheral, thus the peripheral is
not visible and not available. To make an XBUS peripheral visible, its related bit in
XPERCON register must be set before the XPERs are globally enabled with XPEN-bit
in SYSCON register (during system initialization before EINIT instruction).
Note: After reset, no XBUS peripheral is selected in XPERCON register.
XPERCON register is defined as follows:
