CON setting, then any access in the
address range 00’EE00h - 00’EFFFh will
be directed to external memory interface,
using the BUSCONx register correspond-
ing to address matching ADDRSELx regis-
ter. P4.4 and P4.7 can be used as General
Purpose I/O when CAN2 is disabled, and
P4.5 and P4.6 can be used as General
Purpose I/O when CAN1 is disabled.
- The default XPER selection after Reset is
identical
ST10C167: XCAN1 is enabled, XCAN2 is
disabled, XRAM1 (2K Byte compatible
XRAM) is enabled, XRAM2 (new 8K Byte
XRAM) is disabled.

CAN1 Enable Bit
‘0’: Accesses to the on-chip CAN1 XPeripheral and its functions are disabled. P4.5 and P4.6 pins can be
used as general purpose I/Os. Address range 00’EF00h-00’EFFFh is only directed to external memory if
CAN2EN is also ‘0’.
‘1’: The on-chip CAN1 XPeripheral is enabled and can be accessed.
CAN2 Enable Bit
‘0’: Accesses to the on-chip CAN2 XPeripheral and its functions are disabled. P4.4 and P4.7 pins can be
used as general purpose I/Os. Address range 00’EE00h-00’EEFFh is only directed to external memory if
CAN1EN is also ‘0’.
‘1’: The on-chip CAN2 XPeripheral is enabled and can be accessed.
XRAM1 Enable Bit
‘0’: Accesses to external memory within space 00’E000h to 00’E7FFh. The 2K Bytes of internal XRAM1
are disabled.
’1’: Accesses to the internal 2K Bytes of XRAM1.
XRAM2 Enable Bit
‘0’: Accesses to the external memory within space 00’C000h to 00’DFFFh. The 8K Bytes of internal
XRAM2 are disabled.
’1’: Accesses to the internal 8K Bytes of XRAM2.
RTC Enable Bit
’0’: Accesses to the on-chip Real Time Clock are disabled, external access is performed. Address range
00’EC00h-00’ECFFh is only directed to external memory if CAN1EN and CAN2EN are ’0’ also
’1’: The on-chip Real Time Clock is enabled and can be accessed.

- Register XPERCON cannot be changed
after the global enabling of XPeripherals,
i.e. after the setting of bit XPEN in the
SYSCON register.
- In EMUlation mode, all the XPERipherals
are enabled (XPERCON bit are all set).
The access to external memory and/or
XBus is controlled by the bondout chip.
- When the Real Time Clock is disabled
(RTCEN = 0), the clock oscillator is
switch-off
power-down mode. Otherwise, when the
Real Time Clock is enabled, the bit
RTCOFF of the RTCCON register allows
to choose the power-down mode of the
clock oscillator (See Chapter 16 - Real
Time Clock).
