Discrepency with PFS154 fuses versus current datasheet about pdk-includes HOT 3 CLOSED

The Free-PDK information is correct.

The Padauk datasheet is misleading and incomplete. The 'Code Options' table from the datasheet does not correspond 1:1 to a device's fuse-able options.

The real source of truth is actually the PFS154.INC file from the Padauk_Tool. In this file you will see 3 lines that start with .Assembly OPTION [x] inside the .Assembly ASM_INSTR section. These are the actual fuse-able options, where [x] is the start bit of the option. The .Assembly OPTION_VIRTUAL and .Assembly OPTION_MISC2 lines are not part of the fuse-able options, but are configured elsewhere in the MISC, MISC2 and/or MISC_LVR registers found further down in the .INC file.

Here's the relevant (cleaned-up) sections from the PFS154.INC file:

.Assembly	ASM_INSTR	SYM_85A
	.Assembly	OPTION_VIRTUAL:4	LVR	4.0V	3.5V	3.0V	2.75V	2.5V	1.8V	2.2V	2.0V
	.Assembly	OPTION_VIRTUAL	LCD2	Disable	PB0_A034
	.Assembly	OPTION	0	Security	Enable	Disable
	.Assembly	OPTION	8	Drive	Low	Normal
	.Assembly	OPTION	10	Bootup_Time	Slow	X	X	Fast
	.Assembly	OPTION_MISC2		5	Comparator_Edge		All_Edge	Rising_Edge		Falling_Edge
	.Assembly	OPTION_MISC2_SKIP	4	INTRQ_7	TM3 PWMG2
	.Assembly	OPTION_MISC2_SKIP	3	INTRQ_4	COMP PWMG1
	.Assembly	OPTION_LOW	1, 9, 14 ~ 15
	.Assembly	OPTION_DEFAULT	0x3DFD
	.Assembly	OTHER_HIGH

I see, thanks. Not very helpful for the datasheet to describe only how things are presented by the manufacturer development tools, instead of how the chip actually works.

And I was hoping to have a common code base shared between PMS150G and PFS154, without any #ifdef. A foolish aspiration! 😄
