Infinity-Zero (MUTEO)
The SM5877AM outputs an infinity-zero detection
output signal under the following circumstances.
s From immediately after a reset input on RSTN
until the initialization cycle finishes and the first
data cycle occurs.
s When an infinity-zero occurs in the input data.
When an infinity-zero is detected, a period of 214
× (1/fs) ≈ 0.37 seconds takes place before
MUTEO goes HIGH.
