#  CONSOLE_USE_INTERRUPTS (erc32_bsp)
48
#     The erc32 console driver can operate in either polled or interrupt mode.
49
#     Under the simulator (especially when FAST_UART is defined), polled seems
50
#     to operate better.  It is common for a task to print a line (like the
51
#     end of test message) and then exit.  In this case, the program returns
52
#     control to the simulator command line before the program has even queued
53
#     the output to the uart.  Thus sis has no chance of getting the data out.
54
#
55
#  SIMSPARC_FAST_IDLE (erc32_bsp)
56
#     If defined, speed up the clock ticks while the idle task is running so
57
#     time spent in the idle task is minimized.  This significantly reduces
58
#     the wall time required to execute the RTEMS test suites.
59
#
60
#  FPU_REVB (erc32_bsp)
61
#     If defined, enables work-around for bug 3.14 in FPU rev.B or rev.C
