DS1338-33 clock

Put a DS1338-33 clock IC on the board. It is the 3,3 volts 1307. 
Got some help to get soft I2c running, the command $forcesofti2c did the trick. And if you study the history.txt files of the Bascom-AVR updates, you will find this command.



And here the software, with on top a little scan to check if the clock can be found on the soft i2c bus 
$regfile = "xm128a1def.dat" 
$hwstack = 200 
$swstack = 200 
$framesize = 500 
$crystal = 32000000 
 
Config Osc = Enabled , 32mhzosc = Enabled 
Config Sysclock = 32mhz 
 
Config Osc = Disabled , 32mhzosc = Enabled 
Osc_pllctrl = &B10_0_00100 
Do 
Loop Until Osc_status.1 = 1 'Check if RC2MRDY is ready ' 
'enable PLL 
Set Osc_ctrl.4 'PLL enable 
'configure the systemclock 
Config Sysclock = Pll , Prescalea = 1 , Prescalebc = 1_1 'use PLL 
 
Config Priority = Static , Vector = Application , Lo = Enabled , Med = Enabled

Open "COM5:" For Binary As #1 
 
Print #1 , "Start clock"
