◆ priv_ra8_rmac_phy_internal_speed_ok()

bool priv_ra8_rmac_phy_internal_speed_ok	(	ra8_err_t	err,
		uint16_t	reg_value,
		uint16_t	mask )

Pure predicate: PHY register read OK AND mask bit set.

Reusable for both the 1000FULL and 1000HALF speed-decode tests at libs/ra8_hal/src/ra8_rmac_phy.c lines 352 and 356 inside ra8_rmac_phy_link_status_get.

Parameters

[in]	err	Result of the prior MIIM read.
[in]	reg_value	Register value just read.
[in]	mask	Speed-bit mask to test.

Returns: Boolean speed-detected predicate.

Return values

true	Caller may set the corresponding speed enum.
false	Either the read failed or the bit is clear.

Precondition: None.; None.

Postcondition: No state mutated.; Return depends solely on the three inputs.

Note: Test-access only. Pure function.

MC/DC:

2-condition AND; N+1 = 3 vectors:

err=k_ra8_ok, mask&val=0 -> false
err=k_ra8_ok, mask&val=mask -> true (varies right)
err!=k_ra8_ok, mask&val=mask -> false (varies left)

Since: 0.1.0

Pure predicate: PHY register read OK AND mask bit set.

Promoted helper so the line-352/356 AND can be driven under MC/DC.

Parameters

[in]	err	Result of the prior MIIM read.
[in]	reg_value	Register value just read.
[in]	mask	Speed-bit mask to test.

Returns: Boolean predicate.

Return values

true	Speed bit set and read OK.
false	Otherwise.

Precondition: None.; None.

Postcondition: No state mutated.; Return depends solely on inputs.

Note: Pure; thread-safe.

Since: 0.1.0
