| virtual void hw_reset | ( | ) | [pure virtual] |
| virtual unsigned int rd_extcreg_data32 | ( | unsigned char | reg, |
| unsigned char | SPIreadenablecmd | ||
| ) | [pure virtual] |
Read 3x8bit ExtendedCommands register data.
- Parameters:
-
reg the register to read SPIreadenablecmd vendor/device specific cmd to read EXTC registers
- Returns:
- data as uint
- Note:
- EXTC regs (0xB0 to 0xFF) are read/write registers but needs special cmd to be read in SPI mode
