Port Integration Module (S12XSPIMV1)
NOTE
This document assumes the availability of all features (112-pin package
option). Some functions are not available on lower pin count package
options. Refer to the pin-out summary section.
2.1.2 Features
The Port Integration Module includes these distinctive registers:
• Data and data direction registers for Ports A, B, E, K, T, S, M, P, H, J, and AD when used as
general-purpose I/O
• Control registers to enable/disable pull-device and select pull-ups/pull-downs on Ports T, S, M, P,
H, and J on per-pin basis
• Control registers to enable/disable pull-up devices on Port AD on per-pin basis
• Single control register to enable/disable pull-ups on Ports A, B, E, and K on per-port basis and on
BKGD pin
• Control registers to enable/disable reduced output drive on Ports T, S, M, P, H, J, and AD on per-pin
basis
• Single control register to enable/disable reduced output drive on Ports A, B, E, and K on per-port
basis
• Control registers to enable/disable open-drain (wired-or) mode on Ports S, and M
• Interrupt flag register for pin interrupts on Ports P, H, and J
• Control register to configure IRQ pin operation
• Routing registers to support module port relocation
• Free-running clock outputs
A standard port pin has the following minimum features:
• Input/output selection
• 5V output drive with two selectable drive strengths
• 5V digital and analog input
• Input with selectable pull-up or pull-down device
Optional features supported on dedicated pins:
• Open drain for wired-or connections
• Interrupt inputs with glitch filtering
2.2 External Signal Description
This section lists and describes the signals that connect off-chip.
Table 2-1 shows all the pins and their functions that are controlled by the Port Integration Module. Refer
to the device definition for the availability of the individual pins in the different package options.
