HWM90480003 TOP Chapter 3.6 Interrupt by µDMA There might be problems when using µDMA with UART or PPG. 1) Detailed of bug for uDMA transmission Fujitsu found the bug, as uDMA transmission is not operated normally for MB90480/485 series. The bug has two combinations as following. 1.uDMA and UART (Synchronization/Asynchronization) transmission 2.uDMA and PPG Also we have already checked the combination between uDMA and other resource. But there was no bug for other combina

3-3) Countermeasure with combination between uDMA and PPG Fujitsu consider as the restriction of specification for usage with combination between uDMA and PPG. Therefore Fujitsu doesn’t implement permanent countermeasure (hardware revision). Use the interrupt of PPG but not uDMA. hm90480-cm44-10121-7e-corr-x1-00.doc 5 / 5
