System Firmware does not set the Flash timing correctly to account for the higher system clock speed.
Impact: The device can behave unpredictably if the Flash timing is incorrect. The problem is more likely
to occur at higher temperatures.
Workaround: Set the Flash timing manually before calling CP250x_System_Init() to configure the
system clock to 48 MHz:
Resolution: The CP2501-B02-GM System Firmware will set the Flash timing correctly for 48 MHz
operation.

Minor—Workaround exists.
Major—Errata that do not conform to the data sheet or standard.
Information—The device behavior is not ideal but acceptable. Typically, the data sheet will be
changed to match the device behavior.
