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). */ typedef enum { SIO = 1, FT8U232AM = 2, FT232BM = 3, } ftdi_chip_type_t; typedef enum { ftdi_sio_b300 = 0, ftdi_sio_b600 = 1, ftdi_sio_b1200 = 2, ftdi_sio_b2400 = 3, ftdi_sio_b4800 = 4, ftdi_sio_b9600 = 5, ftdi_sio_b19200 = 6, ftdi_sio_b38400 = 7, ftdi_sio_b57600 = 8, ftdi_sio_b115200 = 9 } FTDI_SIO_baudrate_t ; /* * The ftdi_8U232AM_xxMHz_byyy constants have been removed.
