If the host system or the motherboard transmits the following commands in sequence through
the UART serial port, the resulting actions are as follows:
CBh
、
00
Setting refers to "00" register
CCh
、
02
Write data 02 to the "00" register
CAh
、
00
Execute 9A [02], because the "00" register data is 02, so the 9Ah #02 instruction will
be executed, and this means that the instruction is to execute the action of 0x80
0x03, that is, the number 10 is displayed in the (100,100) coordinate image.
CEh
、
00
Add one to the data in the "00" register, so the data in the "00" register
becomes 03.
CAh
、
00
Execute 9A [03], because the "00" register data has become 03, so the 9Ah #03
instruction will be executed, and this means that the instruction is to execute the
action of 0x80 0x04, 0x88 0x00, that is, at (200,100) coordinates Display the picture
number 12 and display GIF0 animation at (400,150) coordinates.
CEh
、
00
Add one to the data in the "00" register, so the data in the "00" register
becomes 04
CAh
、
00
Execute 9A [04], because the "00" register data has changed to 04, so the 9Ah #04
instruction will be executed, and this means that the instruction is to execute the
action of 0x80 0x05, 0xB8 0x00, which is at (300,100) coordinates Display picture
number 20 and play Wav-1 sound.
