* Definitions for the FTDI USB Single Port Serial Converter -
|
|
* known as FTDI_SIO (Serial Input/Output application of the chipset)
|
|
*
|
|
* The example I have is known as the USC-1000 which is available from
|
|
* http://www.dse.co.nz - cat no XH4214 It looks similar to this:
|
|
* http://www.dansdata.com/usbser.htm but I can't be sure There are other
|
|
* USC-1000s which don't look like my device though so beware!
|
|
*
|
|
* The device is based on the FTDI FT8U100AX chip. It has a DB25 on one side,
|
|
* USB on the other.
|
|
*
|
|
* Thanx to FTDI (http://www.ftdi.co.uk) for so kindly providing details
|
|
* of the protocol required to talk to the device and ongoing assistence
|
|
* during development.
|
|
*
|
|
* Bill Ryder - bryder@sgi.com formerly of Silicon Graphics, Inc.- wrote the
|
|
* FTDI_SIO implementation.
|
|
*
|
|
* Philipp Gühring - pg@futureware.at - added the Device ID of the USB relais
|
|
* from Rudolf Gugler

|
|
* wIndex: Port
|
|
* wLength: 0
|
|
* Data: None
|
|
* The BaudDivisor values are calculated as follows:
|
|
* - BaseClock is either 12000000 or 48000000 depending on the device. FIXME: I wish
|
|
* I knew how to detect old chips to select proper base clock!
|
|
* - BaudDivisor is a fixed point number encoded in a funny way.
|
|
* (--WRONG WAY OF THINKING--)
|
|
* BaudDivisor is a fixed point number encoded with following bit weighs:
|
|
* (-2)(-1)(13..0). It is a radical with a denominator of 4, so values
|
|
* end with 0.0 (00...), 0.25 (10...), 0.5 (01...), and 0.75 (11...).
|
|
* (--THE REALITY--)
|
|
* The both-bits-set has quite different meaning from 0.75 - the chip designers
|
|
* have decided it to mean 0.125 instead of 0.75.
|
|
* This info looked up in FTDI application note "FT8U232 DEVICES \ Data Rates
|
|
* and Flow Control Consideration for USB to RS232".
|
|
* - BaudDivisor = (BaseClock / 16) / BaudRate, where the (=) operation should
|
|
* automagically re-encode the resulting value to take fractions into consideration.
|
|
* As all values are integers, some bit twiddling is in order:
|
|
* BaudDivisor = (BaseClock / 16 / BaudRate) |
|
|
* (((BaseClock / 2 / BaudRate) & 4) ? 0x4000 // 0.5
|
|
* : ((BaseClock / 2 / BaudRate) & 2) ? 0x8000 // 0.25
|
|
* : ((BaseClock / 2 / BaudRate) & 1) ? 0xc000 // 0.125
|
|
* : 0)
|
|
*
|
|
* For the FT232BM, a 17th divisor bit was introduced to encode the multiples
|
|
* of 0.125 missing from the FT8U232AM. Bits 16 to 14 are coded as follows
|
|
* (the first four codes are the same as for the FT8U232AM, where bit 16 is
|
|
* always 0):
|
|
* 000 - add .000 to divisor
|
|
* 001 - add .500 to divisor
|
|
* 010 - add .250 to divisor
|
|
* 011 - add .125 to divisor
|
|
* 100 - add .375 to divisor
|
|
* 101 - add .625 to divisor
|
|
* 110 - add .750 to divisor
|
|
* 111 - add .875 to divisor
|
|
* Bits 15 to 0 of the 17-bit divisor are placed in the urb value. Bit 16 is
|
|
* placed in bit 0 of the urb index.
|
|
*
|
|
* Note that there are a couple of special cases to support the highest baud
|
|
* rates. If the calculated divisor value is 1, this needs to be replaced with
|
|
* 0. Additionally for the FT232BM, if the calculated divisor value is 0x4001
|
|
* (1.5), this needs to be replaced with 0x0001 (1) (but this divisor value is
|
|
* not supported by the FT8U232AM).
