F.2.3 Event Based WrMsg Busy Time
The Event based WrMsg busy time is defined as the time it takes for the module to return the
H_WRMSG area to the application after the application has posted a message.
F.2.4 Event Based Process Data Delay
“Read process data delay” is defined as the time from when the last bit of the network frame has been
received by the network interface, to when the RDPDI interrupt is asserted to the application.
“Write process data delay” is defined as the time from when the application exchanges write process
data buffers, to when the first bit of the new process data frame is sent out on the network.
The test was run in 16-bit parallel event mode, with interrupts triggered only for new process data events.
The delay added by the PHY circuit has not been included, as this delay is insignificant compared to the
total process data delay.
