66 / 97 page NuMicro NUC230/240 Datasheet Dec. 30, 2014 Page 66 of 97 Revision 1.01 6.7.2 Features Supports nine PDMA channels and one CRC channel. Each PDMA channel can support a unidirectional transfer AMBA AHB master/slave interface compatible, for data transfer and register read/write Hardware round robin priority scheme. DMA channel 0 has the highest priority and channel 8 has the lowest priority PDMA operation - Peripheral-to-memory, memory-to-peripheral, and memory-to-memory transfer - Supports word/half-word/byte transfer data width from/to peripheral - Supports address direction: increment, fixed. Cyclic Redundancy Check (CRC) - Supports four common polynomials CRC-CCITT, CRC-8, CRC-16, and CRC-32 CRC-CCITT: X 16 + X12 + X5 + 1 CRC-8: X 8 + X2 + X + 1 CRC-16: X 16 + X15 + X2 + 1 CRC-32: X 32 + X26 + X23 + X22 + X16 + X12 + X11 + X10 + X8 + X7 + X5 + X4 + X 2 + X + 1 - Supports programmable CRC seed value. - Supports programmable order reverse setting for input data and CRC checksum. - Supports programmable 1’s complement setting for input data and CRC checksum. - Supports CPU PIO mode or DMA transfer mode. - Supports the follows write data length in CPU PIO mode 8-bit write mode (byte): 1-AHB clock cycle operation. 16-bit write mode (half-word): 2-AHB clock cycle operation. 32-bit write mode (word): 4-AHB clock cycle operation. - Supports byte alignment transfer data length and word alignment transfer source address in CRC DMA mode. 6.8 Timer Controller (TIMER) 6.8.1 Overview The timer controller includes four 32-bit timers, TIMER0 ~ TIMER3, allowing user to easily implement a timer control for applications. The timer can perform functions, such as frequency measurement, delay timing, clock generation, and event counting by external input pins, and interval measurement by external capture pins. |
