void setpagea(unsigned char page);<br />
void setpageb(unsigned char page);<br />
<br />
== Description ==<br />
<br />
The setpagea() and setpageb() functions select which page of memory occupies address space between 0x1000-0x1FFF and 0x2000-0x2FFF respectively.<br />
<br />
The C library '''does not''' use the HLCALL pagein/pageout mechanism; the Spectranet ROM must already be paged in by the '''pagein'''() call. Generally, it does not make sense to manipulate the paged areas from outside code that is already manipulating data in this area.<br />
<br />
The Spectranet memory map is shown in the following diagram. The number before the colon is the page number.<br />
