Advisory VREG: VREG 'Warn Lo/High' Feature Does Not Work as Intended

Revision(s) Affected 0

Details The VREG "Warn Lo/High" feature should not be used or enabled in the F28M35x

Revision 0 devices. Do not set the VREGWARNE bit in the MNMICFG register as it

could negatively affect the VREG output voltage.

Workaround(s) None. This will be fixed in the next revision of the silicon.

Advisory Temperature Sensor: getTempSlope() and getTempOffset() Functions are not

Available on TMX Silicon

Revision(s) Affected 0

Details The getTempSlope() and getTempOffset() functions are not available for use on TMX

silicon.

Workaround(s) None

Advisory EMAC: Resetting EMAC Controller Using SRCR2 Register Does Not Automatically

Reset the Ethernet PHY Via MII_PHYRST Signal

Revision(s) Affected 0

Details Resetting the EMAC controller by setting Bit 28 of the SRCR2 register does not

automatically reset the Ethernet PHY that is connected to the controller via the

MII_PHYRST function on the IO pin.

Workaround(s) The microcontroller signal or pin connected to the Reset pin on the Ethernet PHY should

be configured as a GPIO instead of as an MII_PHYRST peripheral pin; and the GPIO

must be toggled before resetting the EMAC controller. Toggling the GPIO pin (HIGH →

LOW → HIGH) will reset the PHY, assuming the reset for your PHY is an active-low

signal.

Advisory System Control: Clock Configuration Should Not be Changed When There are

Pending/On-going Accesses to Shared RAM (Cx and Sx) or to Analog Subsystem

Revision(s) Affected 0

Details If the clock configuration is being changed (e.g., changing the clock divider for

Cortex™-M3) when there is a pending/on-going access to Shared RAM (Cx/Sx) or to the

Analog Subsystem, the access could generate an error.

Workaround(s) Software should ensure that there is no pending/on-going access to Shared RAM or to

the Analog Subsystem when the clock configuration is being changed.
