4.4.3.2.1.1 RXFOA – Received Frequency Offset versus Intermediate Frequency on Path A (FSK Only)
| Name: | RXFOA |
| Offset: | 0x0A0 |
| Reset: | 0x00 |
The RXFOA register
provides the frequency difference between the selected receive frequency and the
currently received signal on path A. This register is updated continuously if the RX
path A is working. The register is held in the reset state if path A is disabled
(RDPR.PRFLT = 1 or RDPR.PRPTA = 1) or the complete RX
DSP is turned off (RDCR.RDEN = 0).
