Register set
Note:
22.10.1
Note:
176/239
The default XPER selection after Reset is such that CAN1 is enabled, CAN2 is disabled,
XRAM1 (2 Kbyte XRAM) is enabled and XRAM2 (64 Kbyte XRAM) is disabled; all the other
X-Peripherals are disabled after Reset.
Register XPERCON cannot be changed after the global enabling of X-Peripherals, that is,
after setting of bit XPEN in SYSCON register.
In Emulation mode, all the X-Peripherals are enabled (XPERCON bits are all set). The
bondout chip determines whether or not to redirect an access to external memory or to
XBUS.
Reserved bits of XPERCON register are always written to ‘0’.
Table 87
during reset as well as the SYSCON (bit XPEN) and XPERCON (bits XRAM2EN and
XFLASHEN) registers user programmed values.
Table 87.
The symbol “x” in the table above stands for “do not care”.
XPERCON and XPEREMU registers
As already mentioned, the XPERCON register must be programmed to enable the single
XBUS modules separately. The XPERCON is a read/write ESFR register; the XPEREMU
register is a write-only register mapped on XBUS memory space (address EB7Eh).
Once the XPEN bit of SYSCON register is set and at least one of the X-peripherals (except
memories) is activated, the register XPEREMU must be written with the same content of
XPERCON: This is mandatory in order to allow a correct emulation of the new set of
features introduced on XBUS for the new ST10 generation. The following instructions must
be added inside the initialization routine:
Of course, XPEREMU must be programmed after XPERCON and after SYSCON; in this
way the final configuration for X-Peripherals is stored in XPEREMU and used for the
emulation hardware setup.
XPEREMU (EB7Eh)
The bit meaning is exactly the same as in XPERCON.
