Serial Issue

electric550

So when I run the following code with 8Mhz crystal at 8Pll it works fine and increments number in serial terminal slowly, but when I use a 16pll the numbers print out with leading zeros and it prints out a bunch of times instead of one time for each number. The numbers seem to incriment at the right times but each interval is printed out hundreds of times. I am confused as to how this is happening. hardware? Software?

'CON

 _clkmode = xtal1 + pll16x    'Run at the full 80MHz
 _xinfreq = 8_000_000

OBJ
  serial              : "fullduplexserialplus"

DAT

  Ch0 word 1
  Ch1 word 1
  Ch2 word 1
  Time long 1
  oneten byte 1

VAR
  long stack[noparse][[/noparse]40]
  
PUB start | counter, val, count

    'infrared.start(18,17,19)
    'serial.start(25,24,0,115200)
     serial.start(31,30,0,115200)
     count := 0
  repeat
    repeat while count < 500000
      count := count + 1
    count := 0
    counter := counter + 1
    serial.dec(counter)
    serial.tx(10)
    serial.tx(13)

With 8xpll The output in terminal is
1
2
3
4
.
..
...

with 16xpll the output in terminal is
0000000001
00
0000000002
01
0000000002
01
...

0000000003
02
0000000003
02
...

...
0000000004
03
........and so on.

Any help is appreciated. I am not sure why it is happening. Thanks!

16 x 8 MHz is 128 MHz which is beyond the Propeller spec and causing it to behave unreliably. Get a 5 or 6.25 MHz crystal as these are safe to run at 16x.
