  Revision History
  Date      Who  Comment
  ________  ___  _____________________________________________________________
  05/31/00  tbh  initial version
  07/27/01  tbh  tweak port for 20x family
  11/15/01  tbh  added k_external_phy
  11/26/01  tbh  added k_yop_gpio0
  04/05/02  tbh  changed kbm_yop_gpio0 to k_ix_yop_gpio to specify bitix
  04/24/02  tbh  added k_support_otprom
  06/25/02  cds  added k_support_nand & k_support_nvram
  08/06/02  tbh  turned all of the k_support_xxx into k_opt_xxx and removed
                 from this file (this is the wrong place for application settings)
                 and they are now specified in the build scripts as $(OPTn) flags.
  08/20/02  cds  had to have the suspend option be dependent on the k_mcu_xxx... the 210
                 should be 20x style, and the 242 needs to be NIL style for now.  In order
                 to have a single version, the file must switch between the two.
                 There's gotta be a better way to do this...  this could get ugly.
  09/05/02  tbh/ds changed k_ticks_per_usec into k_t0_ticks_per_usec and
                 k_t1_ticks_per_usec since the timers can run on clk/12 or clk/4
                 independently.
  09/20/02  tbh  the 211 doesn't yop.
  09/25/02  rcc  the 242 FPGA supports suspend now so we don't need NIL suspend for it. Lines commented out.
                 as a default we want the yop turned off
  10/31/02  ds   changed the clksel bitmask to suit the new nomenclature in minimos

// specify timer 0 ticks per microsecond required for an interval of 1msec.
// (the timer0 interval must be 1msec.)
// using timer mode 1 (16 bit timer) timer load = 0xFFFF - (1000 * ticks_per_usec)

  // now, the t0 timer is 3 times slower than it should be.
  // but, its too late to fix it because too much has been fine
  // tuned to the current values.  so, for "accurate" timing
  // use timer1, as it has the correct number for clk/12.
