The formal answer.... The MOD5270 has an internal 1.5V supply. The only issue with power is if the 1.5V supply is above the 3.3V supply. One could probably concoct a power up sequence where you power up the 3.3, then pull it down really hard and get the 1.5V over the 3.3V. I don't think any normal s...

Yea you can do glue less 574 for outputs and 537 for inputs. You end up burning one chipselect per device. If you need more than the number of chip selects available then add a 138. The 138 active low enable goes to the chipselect. You can put R/W input one address of the 138 and address into the ot...

You need to add a 574 not a 573.

The 574 is edge triggered and you can use the rising edge of the CS signal with no inverter.

We have a VERY old app note that covers this..

Attached is a bitbang driver for the original PK70 where we failed to bring out the Serial pins. It uses GPIO and will run at 38400 with minimal impact. It could be easily ported to any 5270 or 5234(Use the TPU for 5234) platform. The comments in this code show where one would change things to chang...

Did you change the default Ticks per second?

Do you have any user written interrupts that are watching timers?

Some thing in your code overflowing at 2560000 seconds?

It looks like its happening in an interrupt.
Do you have any user written interrupt routines?

The nop flushes all pending cache operations.

Sounds like an issue with the server not the netburner.
The Netburner only has 32 TCP sockets.


What are you connecting to?

Can you do the same exact test from a PC?
