DRAM Tester Control Registers

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.

Reset																0 PL

				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 66.67MHz, CTR32 will count at a fractional amount faster or slower than 1MHz, depending on the programming of the CLK_FREQUENCY register.
