6.1.1.8 SCRATCH_2
The SCRATCH_2 instruction allows access to the 32-bit read/write Scratchpad 2 Register (SPR2). The SPR2
register is a user storage location, which is reset by the global reset signal. The values stored in this register do not
affect the operation of the DS26900.
6.1.1.9 PORT_RST
The PORT_RST instruction generates a port-specific
STRSTn signal. Port selection must first be performed by
loading an address into the Secondary Port Selection Register (SPSR). The selected
STRSTn signal is asserted
high, asserted low for three (TCLK) clock periods, and then is asserted high. If the SPSR register contains 00000b
or an invalid address, no port reset is generated. The three-clock-period width is a fixed value. Exit from
configuration mode before three clock periods have elapsed can shorten the width of this pulse.
6.1.1.10 NOP
The NOP instruction is “no operation.” It does not perform a function.
6.1.1.11ALL_PORTS_RST
The ALL_PORTS_RST instruction generates a
STRSTn signal to all possible 18 (or 20) ports simultaneously. All
STRSTn signals start by being asserted high, asserted low for three (TCLK) clock periods, and then asserted high.
The three-clock-period width is a fixed value. Exit from configuration mode before three clock periods have elapsed
can shorten the width of this pulse.
