Different kind of signals: - Level - Edge - Pulse - Clock (periodic pulses) Physical view: - High/low level - Rising/falling edge Logical view: - Active/passive Implementations: - Setting a...
That's strange. These vertical patterns typically happens when some timing is off in the shifter logic to copy data from IR to RR, or from upper RRs to lower. This...
It works for me with the latest `master`, d29ef59.
Thank you! This should speed up debugging. Some quick notes: - `loads` should never go beyond 4, since it corresponds to a 4-bit shift register. - But then, raising `LOAD`...
Duh, your patch works, because the code is looking for `loads == 4`! The problem is that the previous scanline ends by loading IR0-2. I'm not sure if this is...
Apparently, it doesn't work with TOS 1.04. However, the video output is still shakey in most of the screens.
I made the menu and the F1 screen happy by adjusting the timing of the Timer B interrupt. These two screens use one Timer B interrupt to switch the video...
I have the GLUE call the MFP to set the Timer B interrupt pending. Then, later, the CPU calls the MFP to trigger pending interrupts. For the HBL and VBL...
F5 with -K runs for a few seconds, then craches with lots of address errors.
F1 became unstable after #123. Log output shows that sometimes the lower border switch to low resolution comes too late. Previously, the switch was done at cycle 28-44. Now, it...
