Hardware Reset API
The reset controller allows software control of the resets to all of the peripherals that are not critical to boot the processor in the RP2040.
Multiple blocks are referred to using a bitmask as follows:
Block to reset | Bit |
USB | 24 |
UART 1 | 23 |
UART 0 | 22 |
Timer | 21 |
TB Manager | 20 |
SysInfo | 19 |
System Config | 18 |
SPI 1 | 17 |
SPI 0 | 16 |
RTC | 15 |
PWM | 14 |
PLL USB | 13 |
PLL System | 12 |
PIO 1 | 11 |
PIO 0 | 10 |
Pads - QSPI | 9 |
Pads - bank 0 | 8 |
JTAG | 7 |
IO Bank 1 | 6 |
IO Bank 0 | 5 |
I2C 1 | 4 |
I2C 0 | 3 |
DMA | 2 |
Bus Control | 1 |
ADC 0 | 0 |
