The tester should not be used by software. The trun and tsse bits (bits 0
and 1 of the register at address $FEF80060) should never be set.
CTR32 CTR32 is a 32-bit, free-running counter that increments
once per microsecond if the CLK_FREQUENCY register
has been programmed properly. Notice that CTR32 is
cleared by power-up and local reset. It does not exist in
Revision 1 of Falcon.
Note
When the system clock is a fractional frequency, such as 66.67
MHz, CTR32 will count at a fractional amount faster or slower
than 1MHz, depending on the programming of the
CLK_FREQUENCY Register.
