Signal Name
PLL_TEST
Refers to pin’s primary function. All pins which are configurable for GPIO have a pullup
enabled in GPIO mode with the exception of PBUSCTL[7], PBUSCTL[4:0], PADDR, PBS,
PSDRAM.
If JTAG_EN is asserted, these pins default to Alternate 1 (JTAG) functionality. The GPIO
module is not responsible for assigning these pins.

MCF5271 Reference Manual, Rev. 2
Primary reset input to the device. Asserting RESET immediately
resets the CPU and peripherals.
Driven low for 128 CPU clocks when the soft reset bit of the system
configuration register (SCR[SOFTRST]) is set. It is driven low for 32K
CPU clocks when the software watchdog timer times out or when a
low input level is applied to RESET.
