Hi, the answer is YES, all of the above. The pins are connected to the APB bus by default for compatibility reasons but can be connected to the Local Bus (memory bus) as well. For the "how" you could check the Users Manual of the LPC2148, which is the first of the Philips devices to use this methode. Robert --- In lp

Hi, Is it possible to read pins with IO0PIN register even is they are mapped to other functions than the GPIO? As far as I know, this is not possible with the LPC2292. With the exception of the ADC pins, I don't know why the pins cannot always be connected to the IO0PIN register. This would be very usefull with reading the state of capture or interrupt

Hi, I searched before posting & didn't find what I was looking for, hopefully this isn't old territory. I will be using the 2101 in a new design. 2k SRAM, 8k flash (2x4k blocks) It seems as though the minimum amount that can be programmed at once (IAP) is 256 bytes, and that the RAM-->flash copy command is what does it. I need to use a portion of the flash as a non-volatile m

Hi! I am using LPC2103 in a new design, and I am confused about the power supply. LPC2101/2/3s have a build-in A/D converter which requires an additional analog power supply (VDD-A and VSS-A, pins 42 and 31 respectively). The manual states that VDD-A powers the analog circuitry but also the build-in PLL... That seems strange to me, as the PLL will introduce high frequency noise on the...

However, this issue is code and code-position dependent, which is why the issue was not immediately apparent in testing . Many customers' code executes at full speed without any issues. It h...
