5.9.1 Chip-Select Registers
M68HC16 Z SERIES
USER’S MANUAL
Chip-select assertion can be synchronized with bus control signals to provide output
enable, read/write strobe, or interrupt acknowledge signals. Logic can also generate
DSACK and AVEC signals internally. A single DSACK generator is shared by all chip-
selects. Each signal can also be synchronized with the ECLK signal available on
ADDR23.
When a memory access occurs, chip-select logic compares address space type, ad-
dress, type of access, transfer size, and interrupt priority (in the case of interrupt ac-
knowledge) to parameters stored in chip-select registers. If all parameters match, the
appropriate chip-select signal is asserted. Select signals are active low. If a chip-select
function is given the same address as a microcontroller module or an internal memory
array, an access to that address goes to the module or array, and the chip-select sig-
nal is not asserted. The external address and data buses do not reflect the internal ac-
cess.
All chip-select circuits are configured for operation out of reset. However, all chip-se-
lect signals except CSBOOT are disabled, and cannot be asserted until the BYTE[1:0]
field in the corresponding option register is programmed to a non-zero value to select
a transfer size. The chip-select option register must not be written until a base address
has been written to a proper base address register. Alternate functions for chip-select
pins are enabled if appropriate data bus pins are held low at the release of RESET.
Refer to
functional diagram of a single chip-select circuit.
Each chip-select pin can have one or more functions. Chip-select pin assignment reg-
isters CSPAR[1:0] determine functions of the pins. Pin assignment registers also de-
termine port size (8- or 16-bit) for dynamic bus allocation. A pin data register (PORTC)
latches data for chip-select pins that are used for discrete output.
