HEllo, I'm trying to configure this IC following the DAta Sheet instructions:
So at first I assert the TZ0 and IWD lines
Then I Move the FSM to IM1 (STATUS register)
Then I configure the DAC (Firing configuration)
Then I try to set ZCNT and TO CNT registers
When I read back all the set of TPIC registers I see that the STATUS and DAC are properly written to my desired values but the counters are all set to their default values:
STATUS = 0x40
DAC = 0x10
ZCNT[0:3] = 0x0A
TOCNT[0:3] = 0xBB
Finally when I setup the Firing sequence I see the counters to go down, ZCNT arrives to zero, so my guess is that the READ works properly and the issue is that OI cannot write such registers.
Am I missing some step in the configuration sequence?
why the TPIC does not let me to change the default values?
