1 BCM datasheet errata. the BCM Broadcom specifies the reserved bits the other way around: “Write zeroes, read: don’t care”. Read about ‘Broadcom: Datasheet for BCM ARM Peripherals’ on element14 .com. Broadcom: Datasheet for BCM ARM Peripherals. If you have been following Raspberry Pi project, you may have noticed the dearth of documentation related to Broadcom processors.

Near the bottom of the page RXR. How do these combine???
BCM2835 datasheet errata
Switch on option for linking, so cross-references and table of contents can be jumped through. If 0 the receiver shift register is cleared before each transaction.
The CDIV value is documented as “must be a power of 2”. Allusions to the APB clock domain are made. This is from Geert Van Loos at the page below:.
I assume you want the cleanest clock source which is the XTAL The second block, with functions starting: I strongly suspect that the CDIV counter is only 14 bits wide. Retrieved from ” https: Another hint is that it says that the bit clears when “sufficient” data is read from the FIFO. Does this mean, that the SYNC bit can also be changed at runtime as well?
This had lead to a confusing picture. Two bits high would be consistent with TX empty and RX empty.

The I2C section on page 34 mentions MHz as a “nominal core clock”. This page broadcomm last edited on 9 Julyat And by specifying “read: However, bits 7 and 9 does not match the original datasheet, nor my guess Many datasheets specify “write: The bottom bit doesn’t work as per specifications, and because the “0” results inthe top bit doesn’t either.
Thus new data is concatenated to old data. Instead of “when all register contents is bc,2835. The Peek register is documented here as being at 0x7ec, whereas the table on page 8 shows 0x7e Possibly the “choice” hasn’t been specified. The mashing dividers are build such that clock artifacts should be pushed out of the audio frequency domain.
This may happen every time this bdm2835 is set, but it is not measurable every time when sampling at 16MHz higher sampling speeds would be needed to confirm that. An easy implementation would implement the 0 value as the maximum divisor. If you expand the hardware the hardware may be enhanced and do “different things” if you write ones to the previously “reserved” bits.

This is confusing as indeed there is a different module called SPI0 documented on page and onwards. The hardware was changed detecting “half full” was difficult?
They should both read “If this bit cleared no new symbols will be Some of the tables from the datasheet have been reproduced here. There is a bug in the I2C master that it does not support clock stretching at arbitrary points. Not as “half the maximum”.
Or the hardware does what I expect: There is amiguity on what register bits can be modified while the I2S system is active.
