HR C5000 Baseband Chip

This fine page will document the HR C5000 radio baseband chip.
Pat Hickey's md380-re project contains a datasheet as hrc5000.pdf. It is an incomplete draft in Chinese, but register descriptions translate rather well and register names are in English.
Note that some registers are missing and some sections of text are incomplete. We'd be very grateful for more recent documentation, or for a proper translation from someone literate in Chinese.
| Type | Address | Name | ||||
|---|---|---|---|---|---|---|
| Reset | 0x00 | W | DMRnRst | 0x00 | Bit7 | 0 DMR Protocol reset |
| PHYnRst | Bit6 | 0 Physical layer reset |
TODO Extract the registers from the datasheet and list them here for convenience when reverse engineering.
HR also offers a HR V3000 voice codec chip, which is just a reprogrammed STM32F303. The MD380 omits this chip, but instead emulates the audio codec in the STM32F405 that doubles as the primary CPU.
