when I used simulator in keil5 for NRF51 software debug, there is a problem : *** error 65: access violation at 0xFFFFFFF4 : no 'write' permission. When I used the
In situations where the memory is 'lightly loaded', such as running some simple tasks alongside I2C/UART buffer handling, I've struggled to reliably measure a performance difference. However in situations where memory access patterns are more intricate and using the DMA peripherals is vital, i.e...
ALE Enable: When set (= 1), this bit enables the ALE signal output during on-chip program and data memory accesses. When clear (= 0), the ALE signal output is disabled during on-chip program and data memory accesses. External memory access automatically enables ALE i...
