system-console: control timing of multiple commands (wait/pause?)

Hello,

I am using batches of commands sent together on the system-console interface. I do need to be able to control the timing of the commands (the device appears to need a very short pause in between each).

1) Is there a pause 1us or X clock cycles, or similar command available that can be sent from the system-console?

In the documentation, I could only find executor_wait_for but it requires a handle (don't have one) and the unit is unclear.

Example of commands sent. The SPI here is tripping and needs a couple extra clock cycles between each write.

master_write_16 {/channels/local/m/master_1} {0x200183a2} {0x049a};
master_write_16 {/channels/local/m/master_1} {0x20018458} {0xe5a7};
master_write_16 {/channels/local/m/master_1} {0x200185a8} {0xba4d};

system-console 12.1

Or is there a better way to do large SPI read/writes (100s at a time?)

2) I can't manage to solve what seems to be a very simple problem. The following code works when I call rreg2 but not rreg.

# TCL script for system console:
proc rreg {master addr} {
	foreach a $addr {
		rreg2 $master $a
    }
}

proc rreg2 {master addr} {
	puts "master_read_16 $master $addr 1;"
	master_read_16 $master $addr 1;
}

Example:

#This works:
rreg2 /channels/local/m/master_1 0x20010200
#This does not work:
rreg  /channels/local/m/master_1 0x20010200

Could you point me to the right direction?

Thank you
