52 / 77 page  Theory of operation STPMC1 52/77 Doc ID 15728 Rev 6 9.17.7 Group 6 data records 6.1 ACR: ● iR RMS SWM accumulator: 20-bit accumulator of R phase current in SWM mode (see paragraph 9.7) ● R-phase elapsed: phase delay (see paragraph 9.15) 6.2 ACS: ● iS RMS SWM accumulator: 20-bit accumulator of S phase current in SWM mode (see paragraph 9.7) ● S-phase elapsed: phase delay (see paragraph 9.15) 6.3 ACT: ● iT RMS SWM accumulator: 20-bit accumulator of T phase current in SWM mode (see paragraph 9.7) ● T-phase elapsed: phase delay (see paragraph 9.15) 6.4 CF3: ● bits [111..84] of configurators (see Table 33) 9.17.8 Parity calculation Each bit of parity nibble is defined as odd parity of all seven corresponding bits of data nibbles. In order to check the data record integrity, the application might execute the following C code, given as an example: int BadParity (unsigned char *bp) {register unsigned char prty = grp;/* temp register set to group # (0..6)*/ prty ^= *bp; /* xor it with 1st byte of data */ prty ^= *(bp+1); /* xor it with the 2nd byte */ prty ^= *(bp+2); /* and with the 3rd byte */ prty ^= *(bp+3); /* and last, with the 4th byte */ prty ^= prty<<4; /* combine */ prty &= 0xF0; /* remove the lower nibble */ return (prty != 0xF0); /* returns 1, if bad parity */} Figure 20.
