Settings: 38400 / 8E2 / MC Protocol Format5 Binary / sum-check on / station 0
Practical family selection: ql

Summary

Area	Current status	Notes
CPU identification	pass	`cpu-model` returns `FX5UC-32MT/D`, `0x4A91`
Contiguous read/write	pass, narrow subset	validated `21`-target subset
Supported-device soak	pass	two `180` second runs passed on the screened subset
Native `0403`	pass	validated on the current setup
Native `1402` words	pass	validated with restore on the current setup
Native `1402` bits	pass	validated with restore on the current setup
Native `0406/1406`	pass	validated with restore on the current setup
Native `0801/0802`	not applicable / unsupported	FX5 serial `3C/4C` command list does not include `0801/0802`; probes returned `0x7E40`
Host/module buffer	not applicable / unsupported	probes returned `0x7E40`, and the FX5 serial `3C/4C` command list does not list `0613`, `1613`, `0601`, or `1601`
Qualified helper/native access	not applicable / unsupported	helper `U3E0\\G10` / `U3E0\\HG20` returned `0x7E40`; native `U3E0\\G10` returned `0x7E43`
`DX/DY`	inaccessible on this path	observed `0x7E43`; FX5 serial `3C/4C` accessible-device table marks them inaccessible
`V/ZR`	not applicable on this path	FX5 serial `3C/4C` accessible-device table marks them inaccessible

Device-family Note

The validated contiguous subset on this target is:

STS10, STC10, STN10, TS10, TC10, TN10
CS10, CC10, CN10
SB10, SW10
X10, Y10
M100, L100, F100
B10, D100, W10, Z10, R100

Keep DX, DY, V, and ZR out of the FX5U serial 3C/4C validated subset.

The FX5 serial communication manual's List of Commands and Functions (3C/4C frame, printed page 718-719) lists 0401/1401, 0403/1402, 0406/1406, remote control, loopback, and 1617, but does not list 0613, 1613, 0601, or 1601.
