Chip Revision Number—Read-only unsigned binary field encoded with the chip revision
number. Smaller values represent earlier versions, while larger values represent later versions.
The zero value represents the original prototype release. Consult factory for current values and
revision.
Part ID—Read-only binary field set to binary 010 identifying the part as Bt8970.
Power Down Mode—Read/write control bit. When set, stops all filter processing and zeros the
transmit output for reduced power consumption. All RAM contents are preserved. The mode
bit is automatically set by RST assertion and upon initial power application. It can be cleared
only by writing a logic zero, at which time filter processing and transmitter operation can
proceed.
HCLK Frequency Select—Read/write binary field selects the frequency of the HCLK output.
