Description
External Clock In. This signal is used as the source clock for the transmit clock of
the internal MAC and PHY. The clock frequency is 25MHz ±50ppm. The XCLK1
signal is also used as the reference clock signal for the internal PLL to generate the
125MHz internal system clock.
External Clock In. Used with XCLK1 pin when another polarity of crystal is needed.
This is unused for a normal clock input.
Normal Mode: UART request to send. Active low output.
During reset: CPU clock select. Select CPU clock source. CPUCLKSEL=0 (normal
mode), the internal PLL clock output is used as the CPU clock source.
CPUCLKSEL=1 (factory reserved test signal).
KS8695P chip reset. Active low input asserted for at least 256 system clock (40ns)
cycles to reset the KS8695P. When in the reset state, all the output pins are tri-
stated and all open drain signals are floating.
Watchdog timer reset output. This signal is asserted for at least 200ms if RESETN
is asserted or when the internal watchdog timer expires.
Normal Mode: ROM/SRAM/FLASH and External I/O output enable. Active low.
When asserted, this signal controls the output enable port of the specified device.
During reset: Watchdog timer reset polarity setting. WRSTPLS=0, Active high;
WRSTPLS=1, Active low. No default.
