This section summarizes the settings for each
operating mode of the MRF89XA to save power, based
on the operations and available functionality. The
timing requirements for switching between modes
described in Section 5.3 “Switching Times and
Procedures”.

MRF89XA Operating Modes
(Includes Power-Saving Mode)
High-Z if Continuous mode is activated; otherwise, Output.
Output if PLL_lock_en = 1; otherwise, High-Z.
Valid logic states must be applied to inputs at all times to avoid unwanted leakage currents.

2.6.1
Table 2-3 lists the different operating modes of the
MRF89XA, which can be used to save power.
2.6.2
Table 2-4 lists the state of the digital I/Os in each of the
above described modes of operation, regardless of the
data operating mode (Continuous, Buffered, or
Packet).
