The TPU Debugger code lists:

static const char *tpu_addr_name[0x1f] = { [0] = "TSP_CTLR1", [1] = "TSP_CTRL2", [*4*] = "TSP_TX_*1*", [*3*] = "TSP_TX_*2*", [*2*] = "TSP_TX_*3*", [5] = "TSP_TX_4", [6] = "TSPACT_L", ......

Was wondering if the numbering is a typo. Could not find documentation online.

Just bringing to your notice for check.

Could you please confirm that items 2,3,4 are not supposed to be in sequence.

Thanks.
