‘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.
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 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 RAM) from 32 to 1024 words.
