Timer Timing
Figure 23 shows the timer input AC timing
2.6.10
Ethernet Timing
This section describes the AC electrical characteristics for the Ethernet interface.
There are programmable delay units (PDU) that should be programmed differently for each Interface to meet timing. There is
a general configuration register 4 (GCR4) used to configure the timing. For additional information, see the MSC8144 Reference
Manual.

Notes:
1.
Program the ETHMDC frequency (fMDC) to a maximum value of 2.5 MHz (400 ns period for tMDC). The value depends on the
source clock and configuration of MIIMCFG[MCS] and UPSMR[MDCP]. For example, for a source clock of 400 MHz, to
achieve fMDC = 2.5 MHz, program MIIMCFG[MCS] = 0x4 and UPSMR[MDCP] = 0. See the MSC8144 Reference Manual for
configuration details.
2.
The value depends on the source clock. For example, for a source clock of 267 MHz, the delay is 70 ns. For a source clock of
333 MHz, the delay is 58 ns.
