Note: If none of the memory specifiers are used when declaring a variable, data specifier will be
set as default by the compiler.

CHAPTER 4
Description This memory specifier allows user to access the I/O Memory space.
Example
' put io_buff in io memory space
dim io_buff as byte io
Description
This memory specifier in combination with (rx, io, data) allows user to
access special function registers. It also instructs compiler to maintain same
identifier in Basic and assembly.
Example
dim io_buff as byte io sfr ' put io_buff in I/O memory space
dim y as char rx sfr ' puts y in Rx space
dim temp as byte data sfr and dim temp as byte sfr are equiva-
lent, and put temp in Extended I/O Space.
Description
If no other memory specifier is used (rx, io, sfr, code or data), the regis-
ter
specifer places variable in Rx space, and instructs compiler to maintain
same identifier in C and assembly.
Example
dim y as char register
