Functional Description
4.5
Logic Signals
To allow interfacing to logic levels other than the 1.2 V core voltage, or any of the analog input and output supplies,
the digital interface signals are referenced to DV_DDIO which is an isolated power domain. DV_DDIO may be supplied
from any voltage ranging from 1.2 V to 3.3 V. Many digital control pins have three states, high (H), low (L), or
floating (F). In order to assert the F or floating state, the pin must be left unconnected or undriven.
4.6
Control Modes
The M08035/M08045 may be configured in four separate control modes. The control mode is determined by the
setting of the MODE_SEL pin as shown in Table 4-1 below.
Table 4-1. Control Mode Setting
MODE_SEL
Control Mode
MODE_SEL = F
MODE_SEL = H
MODE_SEL = L
Hardware Control Mode (HIC)
Four-wire Serial Interface Control Mode (SIC4 or SPI)
Two-wire Serial Interface control Mode (SIC2 or I²C)
Memory Interface Configuration Mode (MIC)
When the reclocker is configured through an external EEPROM
The MIC mode is a subset of the two-wire Interface mode and is initiated by writing to special reserved address
when the device is set in two-wire Interface mode.
