VNI8200XP SPI operation (SEL2 = H)
voltage falls below 80% of the nominal V
FB
voltage, this bit is zero; TWARN (IC warning
case temperature, see Section 9.8), PC (parity check fail, the bit, set to ‘1’, indicates a PC
fail or the length is not a multiple of 8) and PG
(Power Good, see Section 9.10). The last 4
bits are used as parity check bits and communication error condition (see command 16 bit
frame):
P0 = F0 ⊕ F1 ⊕ F2 ⊕ F3 ⊕ F4 ⊕ F5 ⊕ F6 ⊕ F7
P1 = PC ⊕ FB_OK ⊕ F1 ⊕ F3 ⊕ F5 ⊕ F7
P2 = PG
⊕ TWARN ⊕ F0 ⊕ F2 ⊕ F4 ⊕ F6
nP0 = NOT P0
Channel indications are latched and cleared after a communication only.
