MASTER/SLAVE PCLK MODES
The parallel ports can operate in either master or slave mode.
The mode is set via PCLK master mode bit in the Parallel Port
Control 2 register. The parallel ports power up in slave mode to
avoid possible contentions on the PCLK pin.
In master mode, PCLK is an output derived by dividing
PLL_CLK down by the PCLK divisor. The PCLK divisor can
have a value of 1, 2, 4, or 8, depending on the 2-bit PCLK
divisor word setting in the Parallel Port Control 2 register. The
highest PLCK rate in master mode is 200 MHz. Master mode is
selected by setting the PCLK master mode bit in the Parallel
Port Control 2 register.

In slave mode, external circuitry provides the PCLK signal.
Slave mode PCLK signals can be either synchronous or
asynchronous. The maximum slave mode PCLK frequency is
also 200 MHz.
