SHDN
FQ[1:0]
Selects operating mode: normal/shutdown
Depth of fault queue⁽¹⁹⁾
1 = shutdown, 0 = normal
[00] = 1, [01] = 2, [10] = 4, [11] = 6
RES[1:0]
A/D converter resolution for external zone; affects conversion rate
[00] = 9-bits, [01] = 10-bits,
[10] = 11-bits, [11] = 12-bits
D[1]
Reserved
Always write as zero
RST
Resets all MIC280 functions and restores the power-up default state
Write only; 1 = reset, 0 = normal
Operation; disabled by setting L4
Note:
19. Any write to CONFIG will result in the fault queues being purged and reset and any A/D conversion in progress being aborted and the result
discarded. The A/D will begin a new conversion sequence once the write operation is complete.
Power-up default value: 1000 0000_b = 80_h (not in shutdown mode; interrupts enabled; fault queue depth = 1; resolution =
9-bits)
Read/write command byte: 0000 0011_b = 03_h
