Programmable Registers
Address:
Re-
27.5.11 I2C Controller DMA Read and Write Data Register
The I2C Controller DMA Read and Write Data Register is the target for both source and
destination DMA and PIO transfers.
DMA reads and writes are directed to this register.
EXAMPLE
The DMA data register is used by the DMA to read or write data from the I2C controller, as
mediated by the I2C controller's DMA request signal.
Address:
Re-
27.5.12 I2C Device Debug Register 0 (HW_I2C_DEBUG0)
The I2C Device Debug Register 0 provides a diagnostic view into various internal states
and controls.
