PRODUCTION DATA.
The PLL1_CTRL0 register provides control of PLL1. The PLL1_CTRL0 register fields are described in the following table.
Bit # | Field | Type | Reset | EEPROM | Description | |
---|---|---|---|---|---|---|
[7:5] | RESERVED | - | - | N | Reserved. | |
[4:2] | PLL1_P[2:0] | RW | 0x7 | Y | PLL1 Post-Divider. The PLL1_P field selects the PLL1 post-divider value as follows. | |
PLL1_P | Post Divider Value | |||||
0 (0x0) | 2 | |||||
1 (0x1) | 2 | |||||
2 (0x2) | 3 | |||||
3 (0x3) | 4 | |||||
4 (0x4) | 5 | |||||
5 (0x5) | 6 | |||||
6 (0x6) | 7 | |||||
7 (0x7) | 8 | |||||
[1] | PLL1_SYNC_EN | RW | 1 | Y | PLL1 SYNC Enable. If PLL1_SYNC_EN is 1 then a SYNC event will cause all channels which use PLL1 as a clock source to be re-synchronized. | |
[0] | PLL1_PDN | RW | 0 | Y | PLL1 Powerdown. The PLL1_PDN bit determines whether PLL1 is automatically enabled and calibrated after a hardware reset. If the PLL1_PDN bit is set to 1 during normal operation then PLL1 is disabled and the calibration circuit is reset. When PLL1_PDN is then cleared to 0 PLL is re-enabled and the calibration sequence is automatically restarted. | |
PLL1_PDN | PLL1 STATE | |||||
0 | PLL1 Enabled | |||||
1 | PLL1 Disabled |
