SGPIO inverted clock qualifier Hi, With bits 6:5 of SGPIO_MUX_CFG the QUALIFIER_MODE is selected (0x0=enable, 0x1=disable, 0x2=slice, 0x3=pin).With bit 8 (INV_QUALIFIER) of SLICE_MUX_CFG one can invert the qualifier (0x0=normal qualifier, 0x1=inverte…

LPC43xx SGPIO Configuration The LPC43xx SGPIO peripheral is used to move samples between USB and the ADC/DAC chip (MAX5864). The SGPIO is a peripheral that has a bunch of 32-bit shift registers. These shift registers can be configured to act as a par…

LPC4350 SGPIO Experimentation The NXP LPC43xx microcontrollers have an interesting, programmable serial peripheral called the SGPIO (Serial GPIO). It consists of a slew of counters and shift registers that can be configured to serialize and deseriali…

The SGPIO output pins SGPIO14 and SGPIO15 can trigger a GPDMA request SGPIO pins SGPIO14 and SGPIO15 can trigger a GPDMA request. < Output = '1' > To generate the request, program a pulse in the bit stream of slice 14 or 15. For example, use a patte…

I²C SGPIO Configuration SGPIO is a hardware feature of LPC4300 series. There are 16 SGPIO pins called from SGPIO 0 to SGPIO 15. SGPIO is one of the functions of LPC 4300 pins which can be chosen. SGPIO could work as standard GPIO pins, or do stream p…

模式匹配 所有位串均具有模式匹配功能. 该功能可用于检测启动代码等.要使用该功能,则必须用需匹配的模式来对REG_SS 编程 (请注意, POS 达到零时 REG_SS 不会与 REG  交换!) MATCH_MODE 位必须设为1. 输入数据 REG 现在与已编程的模式 REG_SS 相比较.发现匹配时会提出模式匹配中断. Bit MATCH_MODE selects whether the match filter is active or whether data is captured.…

Test access port (TAP) JTAG defines a TAP (Test access port). The TAP is a general-purpose port that can provide access to many test support functions built into a component. It is composed as a minimum of the three input connections (TDI, TCK, TMS)…

Q LPC43xx和LPC18xx有相同的USB接口以及片内USB驱动吗?A 是的. Q LPC4300和LPC1800只是内核不同吗?外设和管脚配置都完全一致?A 为LPC18xx的映像可以直接在LPC43xx(尾号一致)上运行,但是LPC4300的片上RAM比LPC1800多64KB,并且LPC1800系列没有SGPIO,而LPC4300有 Q SGPIO是什么?和普通的GPIO有什么不同?A SGPIO是串行GPIO的简称,只要设置好参数就可以根据时钟基准自动按照预设的时序要求,在合适的时…
