PROBLEM DEFINITION
Intraspoke DMA transfers are limited to a one byte burst length.
TRIGGER CONDITION(S)
Intraspoke DMA transfer configured for greater than one byte burst length.
SCOPE OF IMPACT
Data becoming corrupted during DMA transfer.
WORKAROUND
Limit DMA transactions to one byte burst length transfers. Refer to Table 7-2 in the PHUB section
(Section 7.1) of the PSoC 3 Technical Reference Manual to determine if both peripherals are on the same
spoke.
FIX STATUS
Silicon revision fix confirmed in production silicon.
PROBLEM DEFINITION
The CAN controller does not respond properly to a RX short to ground condition (Bus Off behavior). Glitch
filtering does not meet certification requirements.
PARAMETERS AFFECTED
NA
TRIGGER CONDITION(S)
RX short to ground. Electrically noisy environment.
SCOPE OF IMPACT
No impact for user software development. Affects testing and certification for production.
WORKAROUND
None.
FIX STATUS
Silicon revision fix confirmed in production silicon.
PROBLEM DEFINITION
When routing the 1.024 V reference into a opamp results in an incorrect voltage output if the power mode is
configured for anything other then mode 0x00.
TRIGGER CONDITION(S)
Rotuing the 1.024 V reference voltage to an opamp on the device.
SCOPE OF IMPACT
Output of opamp will deviate from expected value of 1.024 V.
WORKAROUND
Configure opamp power mode using the Opamp_SetPower() API into the required power mode of 0x00.
FIX STATUS
Silicon revision fix confirmed in production silicon.
