* Reentrancy checks removed - ultimately this should be in the Kernel.

Version 0.18, 4.5.2.1. Tagged as 'IIC-0_18-4_5_2_1'

Detail:
	Customer F 8 includes the IIC module, and the resources were not being
copied in the build due to there being no Japanese versions of them.
Component has been altered to use LocalRes so that the UK resources are used
if suitable Locale-based ones are not pesent.
Admin:
	Tested locally.

Version 0.18. Tagged as 'IIC-0_18'

Detail:
  A new error, "IIC operation in progress", error number &20301 will be
  returned from SWI IIC_Control under the following circumstances:

  1) if the previous call to IIC_Control has not yet completed; or
  2) if an examination of the interrupt stack indicates that the kernel's
     IIC code is currently threaded. This aspect of operation requires
     detailed knowledge of the kernel; currently the following kernels are
     supported:
       4.52 (featured in STB-22)
       4.71 (featured in STB-3)
       5.31 (featured in STB-400)
     The knowledge required is the range of addresses covering the routines
     HexToBCD to ReadTime from Kernel.s.PMF.i2cutils. It is also assumed
     that kernels from 4.81 onwards feature an Ursula-style 32-bit
     compatible IRQ stack, rather than an ARM2/3 compatible stack with a
     combined return PC/PSR on the stack.

  32-bit compatibility makes heavy use of the No26bitCode switch, largely
  for consistency with the equivalent code in the kernel, with which it
  obviously shares a common heritage.

Admin:
  Currently tested only on an STB-22. Required for closed captioning support
  on all STBs.

  It is currently planned that future versions of RISC OS will farm out IIC
  operations to the HAL, so at that point the distinction between the two
  sets of IIC code will be removed. Ideally, the new IIC code would be
  fully re-entrant (ie would complete any foreground IIC operation, then
  do the background operation and then return to the background process).
  We can just about do without that functionality at present.

Version 0.17. Tagged as 'IIC-0_17'

Detail:
	When merging the Spinner branch of this module, I changed two TAB
characters in the help string to spaces. This threw out the formatting of the
rommodules listing. Fixed by changing back to two TAB's as was present before
the last change.
Admin:
	Tested.

Version 0.16. Tagged as 'IIC-0_16'

Detail:
	Merged Ursula branch.
	Placed component under srccommit control.
	Strdepend now used in clean target.

 Admin:
 	Built.
