The pins used for interfacing the compliant external devices may be multiplexed with PIO lines.
The programmer must first program the PIO controllers to assign the MACB pins to their periph-
eral functions.
The MACB clock is generated by the Power Manager. Before using the MACB, the programmer
must ensure that the MACB clock is enabled in the Power Manager.
In the MACB description, Master Clock (MCK) is the clock of the peripheral bus to which the
MACB is connected.
The synchronization module in the MACB requires that the bus clock (hclk) runs on at least the
speed of the macb_tx/rx_clk, which is 25MHz in 100Mbps, and 2.5MHZ in 10Mbps in MII mode
and 50MHz in 100Mbps, and 5MHZ in 10Mbps in RMII mode.
To prevent bus errors the MACB operation must be terminated before entering sleep mode.
