Value | Description |
---|---|
0x0 | Clear not enabled |
0x1 | Clear on falling edge on DEN1 enabled |
0x2 | Clear on falling edge on DEN2 enabled |
0x3 | Clear on falling edge on either DEN1 or DEN2 enabled |
Bits 18:16 – ISIZE[2:0] Input Data Size
Value | Name | Description |
---|---|---|
0x0 | 8BITS | Input data bus size is 8 bits |
0x1 | 10BITS | Input data bus size is 10 bits |
0x2 | 12BITS | Input data bus size is 12 bits |
0x3 | 14BITS | Input data bus size is 14 bits |
Bit 11 – FRSTS First Sample
This bit is useful only if the HALFS bit is set to 1. If data are numbered in the order that they are received with an index from 0 to n.
Value | Description |
---|---|
0 | Only data with an even index are sampled. |
1 | Only data with an odd index are sampled. |
Bit 10 – HALFS Half Sampling
Value | Description |
---|---|
0 | The Parallel Capture Controller samples all the data. |
1 | The Parallel Capture Controller samples the data only every other time. |
Bit 9 – ALWYS Always Sampling
Value | Description |
---|---|
0 | The parallel capture Controller samples the data when both data enables are active. |
1 | The parallel capture controller always samples the data, regardless of the state of data enable. |
Bit 8 – SCALE Scale Data
Value | Description |
---|---|
0 | No effect. |
1 | When input data size is not equal to 8 bits (ISIZE ≠ 0), the data stored in the PCC_RHR is automatically up-scaled to 16 bits. |
Bits 5:4 – DSIZE[1:0] Data Size
Value | Name | Description |
---|---|---|
0x0 | 1DATA | 1 data is read in the PCC_RHR |
0x1 | 2DATA | 2 data are read in the PCC_RHR |
0x2 | 4DATA | 4 data are read in the PCC_RHR (only for 8 bits data size, ISIZE = 0) |
0x3 | - | Reserved |
Bit 0 – PCEN Parallel Capture Enable
Value | Description |
---|---|
0 | The Parallel Capture Controller is disabled. |
1 | The Parallel Capture Controller is enabled. |
