PRODUCTION DATA.
The CONFIGA Register provides control of the SPI operation. The data written to this register must always be symmetrical otherwise the write will not take place, that is, Bit0=Bit7, Bit1=Bit6, Bit2=Bit5, Bit3=Bit4. Return to Register Map.
BIT NO. | FIELD | TYPE | RESET | DESCRIPTION |
---|---|---|---|---|
[7] | SWRST | RWSC | 0 | Software Reset. Writing a 1 to SWRST resets the device apart from the SPI programmable registers. SWRST is automatically cleared to 0. |
[6] | LSB_FIRST | RW | 0 | Least Significant Bit First. This feature is not support, register data is always transmitted MSB first. |
[5] | ADDR_ASCEND | RW | 0 | Address Increment Ascending. When set to 1 the address in streaming transactions is incremented by 1 after each data byte. When set to 0 the address is decremented by 1 in streaming transactions. |
[4] | SDO_ACTIVE | RW | 0 | SDO Active. SDO is always active. This bit always reads 1. |
[3] | SDO_ACTIVE_CPY | RW | 0 | SDO Active. Must be programmed equal to bit 4. |
[2] | ADDR_ASCEND_CPY | RW | 0 | Address Increment Ascending. Must be programmed equal to bit 5. |
[1] | LSB_FIRST_CPY | RW | 0 | Least Significant Bit First. Must be programmed equal to bit 6. |
[0] | SWRST_CPY | RWSC | 0 | Software Reset. Must be programmed equal to bit 7. |
