This method should only used very simple applications (few characters, displayed times) rapid evaluation. following block code shows direct code patching display character digit where value (digit disp_A_0 9.5.2 Indexed Data mapped values character sets defined into ST6240 Data area (refer ST6240 databook). AST6/LST6 .byte directive labels define access Data area. generic display call subroutine accesses character definition through parameter passed calling program. disp_0 subroutine (see below) displays character digit clears digit (MSB same locations). efficient generic display subroutine should manage digit number input parameter) perform read/modify/write only concerned nibble byte (MSB LSB). This done display subroutine delivered with ST6240 Starter library (please read README file provided SK6240LIB directory). character defined words bits. optimize character size Data ROM, useful compact these bits into bytes, however this method increases display routine complexity. ;value digit COM1 addr (E1, LSB) ;value digit COM2 addr (E7, LSB) ;value digit COM3 addr (ED, LSB) ;value digit COM4 addr (F3, LSB)

Interface
ST6240 Starter demo routines, character defined follows (for example character CHAR_A. .byte .byte .byte .byte character displayed using following routine: disp_A_0 RWSR, CHAR_A.w;set Data Window register CHAR_A.d call disp_0 disp_0 point CHAR_A ;subroutine that displays digit output value digit COM1 ;(E1, LSB) second byte CHAR_A ;output value digit COM2 ;(E7, LSB) third byte CHAR_A ;output value digit COM3 ;(ED, LSB) fourth byte CHAR_A ;output value digit COM4 ;(F3, LSB)
Four bytes used define character, with equal definition values. this way, easily distinguished using instruction masking non-relevant nibble. 9.5.3 Complete Message Display simplify definition complete messages using AST6 .ASCIZ directive. This directive returns ASCII code pattern characters indicated ended NULL). enable .ASCIZ directive, ST6240 character pre-defined Data that becomes simple access mapped character definition through character's ASCII code. Data window contains bytes. character definition requires bytes, characters defined whole window. This corresponds page ASCII codes (represented ASCII code).

This allows asci_dis subroutine display character defined ASCII code Mdis_mes subroutine display complete message, built using ASCIZ AST6 directive, panel.
