Freescale Semiconductor
12.3.2.1 ESSI Transmit Clock (SCK)
This pin can be configured as either an input or an output pin. This clock signal is used by all the
enabled transmitters and the receiver in Synchronous modes or by Transmitter 0 in Asynchronous
modes. Please see Table 12-3 for details about how to configure this pin.
Note:
Although an external serial clock can be independent of and asynchronous to the
system clock, the external ESSI clock frequency must not exceed FIPBus_CLK/4, and
each ESSI clock phase must exceed the minimum of 1.5 IPBus_CLK cycles.
12.3.2.2 ESSI Serial Control Signal 0 (SC0)
The function of this signal is determined by the programmer selecting either Synchronous or
Asynchronous mode, according to data in Table 12-4. In Asynchronous mode, this signal is used
for the receive clock I/O. In Synchronous mode, this signal is used as the transmitter data out
