From ca89989d057a19b647514656d96d00ff23be9640 Mon Sep 17 00:00:00 2001 From: mrb0nk500 Date: Sat, 30 Nov 2019 19:57:46 -0500 Subject: Start work on rev2 of Sux. Added a prefix byte to tell the CPU certain information such as, how many bytes to load into the registers, or what ISA extension we want to use. I also added an assembly language monitor, so that I don't have to write stuff in machine code. --- test/test.s | 13 +++++++++++++ 1 file changed, 13 insertions(+) create mode 100644 test/test.s (limited to 'test') diff --git a/test/test.s b/test/test.s new file mode 100644 index 0000000..3e8a7f2 --- /dev/null +++ b/test/test.s @@ -0,0 +1,13 @@ +; Testing Sux assembly, and the machine language monitor. +; +; Writen by mr b0nk 500 +.org $8000 +cps ; Clear the processor status register. +lda.w #$1000 ; Load 0x1000 into the accumulator. +rol #$1 ; Then rotate the accumulator left by 1 bit. +jmp $8006 ; And then loop. + +.org $FFC0 ; Reset vector. +.qword $8000 +done + -- cgit v1.2.3-13-gbd6f
