Write configuration control (inverted copy of WRC bit of RP0H)
‘0’: Pins WR and BHE retain their normal function.
‘1’: Pin WR acts as WRL, pin BHE acts as WRH.
System clock output enable (CLKOUT)
‘0’: CLKOUT disabled, pin may be used for general purpose I/O.
‘1’: CLKOUT enabled, pin outputs the system clock signal or a prescaled value of
system clock according to XCLKOUTDIV register setting.
Disable/enable control for pin BHE (set according to data bus width)
‘0’: Pin BHE enabled.
‘1’: Pin BHE disabled, pin may be used for general purpose I/O.
Internal memory enable (set according to pin EA during reset)
‘0’: Internal memory disabled: Accesses to the IFlash Memory area use the
external bus.
‘1’: Internal memory enabled.
Segmentation disable/enable control
‘0’: Segmentation enabled (CSP is saved/restored during interrupt entry/exit).
‘1’: Segmentation disabled (Only IP is saved/restored).
Internal memory mapping
‘0’: Internal memory area mapped to segment 0 (00’0000h...00’7FFFh).
‘1’: Internal memory area mapped to segment 1 (01’0000h...01’7FFFh).
System stack size
Selects the size of the system stack (in the internal I-RAM) from 32 to 1024 words.
