24.0.7
24.0.7.1
The BKGD pin is associated with the S12X_BDM and S12X_EBI modules. During reset, the
BKGD pin is used as MODC input.
24.0.7.2
Port A pins PA[7:0] and Port B pins PB[7:0] can be used for either general-purpose I/O.
24.0.7.3
Port E pins PE[7:2] can be used for either general-purpose I/O or with the alternative functions.
Port E pin PE[7] an be used for either general-purpose I/O or as the free-running clock ECLKX2
output running at the core clock rate. The clock output is always enabled in emulation modes.
Port E pin PE[4] an be used for either general-purpose I/O or as the free-running clock ECLK
output running at the bus clock rate or at the programmed divided clock rate. The clock output is
always enabled in emulation modes.
Port E pin PE[1] can be used for either general-purpose input or as the level- or falling edge-
sensitive IRQ interrupt input. IRQ will be enabled by setting the IRQEN configuration bit
(Section 24.0.5.10, “IRQ Control Register
code register. It is inhibited at reset so this pin is initially configured as a simple input with a pull-
up.
Port E pin PE[0] can be used for either general-purpose input or as the level-sensitive XIRQ
interrupt input. XIRQ can be enabled by clearing the X-bit in the CPU’s condition code register. It
is inhibited at reset so this pin is initially configured as a high-impedance input with a pull-up.
24.0.7.4
Port K pins PK[7:0] can be used for either general-purpose I/O.
