2.4.7 Special Pull Resistor Disable Control (SPRDS)
2.4.8 Pin Reset States
MPC555
USER’S MANUAL
IRQ[0]/SGPIOC[0]
For the pins that support debug and opcode-tracking functionality, the pull-up and pull-
down resistors are controlled by the SPRDS signal, which is somewhat like the encod-
ed 3-V / 5-V select. During reset this signal is used synchronously to enable the pull-
up resistors in the pads. On negation of reset, based on which functionality is selected
for the pins, this signal is set to disable the pull-up resistors or remains held in its reset
state to indicate that the pull-ups are disabled only when the output driver is enabled.
For example, if a pin is configured as a bus arbitration pin, The SPRDS signal remains
low throughout reset. This causes the pull-up to be enabled. When reset is released,
SPRDS remains low. The output enable for the driver is negated by default. When the
output driver is enabled, the pull-up is disabled.
When a pin is configured as an opcode-tracking or debug pin, SPRDS remains low
throughout reset. This causes the pull-up to be enabled. When reset is released,
SPRDS is asserted. This disables the pull-up resistor immediately. The output driver
drives the pin to the required state after reset.
