Pin Functions
Table 21-1. External System Pins Associated With MEBI
MC9S12HZ256 Data Sheet, Rev. 2.05
At the rising edge on RESET, the state of this pin is registered into the MODC
bit to set the mode. (This pin always has an internal pullup.)
Pseudo open-drain communication pin for the single-wire background debug
mode. There is an internal pull-up resistor on this pin.
When instruction tagging is on, a 0 at the falling edge of E tags the high half of
the instruction word being read into the instruction queue.
General-purpose I/O pins, see PORTA and DDRA registers.
High-order address lines multiplexed during ECLK low. Outputs except in
special peripheral mode where they are inputs from an external tester system.
High-order bidirectional data lines multiplexed during ECLK high in expanded
wide modes, special peripheral mode, and visible internal accesses (IVIS = 1)
in emulation expanded narrow mode. Direction of data transfer is generally
indicated by R/W.
Alternate high-order and low-order bytes of the bidirectional data lines
multiplexed during ECLK high in expanded narrow modes and narrow accesses
in wide modes. Direction of data transfer is generally indicated by R/W.
General-purpose I/O pins, see PORTB and DDRB registers.
Low-order address lines multiplexed during ECLK low. Outputs except in
special peripheral mode where they are inputs from an external tester system.
Low-order bidirectional data lines multiplexed during ECLK high in expanded
wide modes, special peripheral mode, and visible internal accesses (with
IVIS = 1) in emulation expanded narrow mode. Direction of data transfer is
generally indicated by R/W.
General-purpose I/O pin, see PORTE and DDRE registers.
CPU No Access output. Indicates whether the current cycle is a free cycle. Only
available in expanded modes.
At the rising edge of RESET, the state of this pin is registered into the MODB
bit to set the mode.
General-purpose I/O pin, see PORTE and DDRE registers.
Instruction pipe status bit 1, enabled by PIPOE bit in PEAR.
System clock test output. Only available in special modes. PIPOE = 1 overrides
this function. The enable for this function is in the clock module.
At the rising edge on RESET, the state of this pin is registered into the MODA
bit to set the mode.
General-purpose I/O pin, see PORTE and DDRE registers.
Instruction pipe status bit 0, enabled by PIPOE bit in PEAR.
