Table 28-9. SPI Global Control Register 0 (SPIGCR0) Field Descriptions
Bit Field Value Description
31-1 Reserved 0 Reads return 0. Writes have no effect.
0 nRESET This is the local reset control for the module. This bit needs to be set to 1 before any operation on SPI /
MibSPI can be done. Only after setting this bit to 1, the Auto Initialization of Multi-buffer RAM starts.
Clearing this bit to 0 will result in all of the control and status register values to return to their default
values..
0 SPI is in the reset state.
1 SPI is out of the reset state.
