REGISTER SUMMARY
M68HC16 Z SERIES
D-16
USER’S MANUAL
This register contains seven 2-bit fields that determine the function of corresponding
chip-select pins. Bits [15:14] are not used. These bits always read zero; writes have
no effect. CSPAR0 bit 1 always reads one; writes to CSPAR0 bit 1 have no effect. The
alternate functions can be enabled by data bus mode selection during reset. This reg-
ister may be read or written at any time. After reset, software may enable one or more
pins as discrete outputs.
Table D-9 shows CSPAR0 pin assignments.
CSPAR1 contains five 2-bit fields that determine the functions of corresponding chip-
select pins. Bits [15:10] are not used. These bits always read zero; writes have no ef-
fect. Table D-10 shows CSPAR1 pin assignments, including alternate functions that
can be enabled by data bus mode selection during reset.
