Function
XBUS Peripheral Enable Bit
‘0’: Accesses to the on-chip X-Peripherals and their functions are
disabled.
‘1’: The on-chip X-Peripherals are enabled and can be accessed.
Reset Output Enable Bit
‘0’: The contrast reduction signal is driven on pin 104.
‘1’: The reset output signal is driven on pin 104, i.e. pin 104 is pulled
low during internal reset sequence.
Note: Refer also to Chapter 6.7
Select Line Configuration Control
‘0’: Latched select line mode for X-Peripherals.
‘1’: Select lines for access cycles via XBUS are directly derived from
the address lines.
Note: CSCFG = ‘1’ is recommended. The effect of the switch is not
visible at an external interface.
PM-Bus Enable Bit
‘0’: PM-Bus disabled: accesses to the ROM area use the XBUS.
‘1’: PM-Bus enabled: PM-Bus enabled for access cycles to the ROM
area.
Note: The recommended value ROMEN = ‘1’ is set by hardware during
reset.
Segmentation Disable/Enable Control
‘0’: Segmentation enabled (CSP is saved/restored during interrupt
entry/exit).
‘1’: Segmentation disabled (Only IP is saved/restored).
