38.11.7 TPIU formatter synchronization counter register (TPIU_FSCR)
Address offset: 0x308
Reset value: 0x0000 0040
38.11.8 TPIU claim tag set register (TPIU_CLAIMSETR)
Address offset: 0xFA0
Reset value: 0x0000 000F
Bits 31:9 Reserved, must be kept at reset value.
Bit 8 TRIGIN: trigger on trigger in
1: Indicates a trigger in the trace stream when the TRIGIN input is asserted.
Bits 7:2 Reserved, must be kept at reset value.
Bit 1 ENFCONT: continuous formatting enable
Setting this bit to 0 in SWO mode bypasses the formatter and only ITM/DWT trace is output.
0: Continuous formatting disabled
1: Continuous formatting enabled
Bit 0 Reserved, must be kept at reset value.

This counter contains the number of formatter frames since the last synchronization packet of
128 bits. It is a 12-bit counter with a maximum count value of 4096. This equates to
synchronization every 65536 bytes, that is, 4096 packets x 16 bytes per packet. The default
is set up for a synchronization packet every 1024 bytes, that is, every 64 formatter frames. If
the formatter is configured for continuous mode, full and half-word sync frames are inserted
during normal operation. Under these circumstances, the count value is the maximum
number of complete frames between full synchronization packets.
