PRODUCTION DATA.
Table 6-32 describes the bit fields of the Collision Position and Interrupt Mask register.
Default Value: 0x3E, set at POR = H and EN = L. Collision bits reset automatically after read operation.
| BIT NO. | BIT NAME | FUNCTION | DESCRIPTION |
|---|---|---|---|
| B7 | Col9 | Bit position of collision MSB | Supports ISO/IEC 14443 A |
| B6 | Col8 | Bit position of collision | |
| B5 | En_irq_fifo | Interrupt enable for FIFO | Default = 1 |
| B4 | En_irq_err1 | Interrupt enable for CRC | Default = 1 |
| B3 | En_irq_err2 | Interrupt enable for Parity | Default = 1 |
| B2 | En_irq_err3 | Interrupt enable for Framing error or EOF | Default = 1 |
| B1 | En_irq_col | Interrupt enable for collision error | Default = 1 |
| B0 | En_irq_noresp | Enables no response interrupt | Default = 0 |
Table 6-33 describes the bit fields of the Collision Position register. This register displays the bit position of collision or error.
Default Value: 0x00, set at POR = H and EN = L. The register is also automatically reset after a read.
| BIT NO. | BIT NAME | FUNCTION | DESCRIPTION |
|---|---|---|---|
| B7 | Col7 | Bit position of collision. B7 is the MSB. | ISO/IEC 14443 A mainly supported; in the other protocols, this register shows the bit position of error. Either frame, SOF/EOF, parity, or CRC error. |
