The Dynamic C library functions
IBIT
,
ISET
, and
IRES
in the
BIOS.LIB
library allow bits in the I/O registers to be tested, set, and cleared. Both
16-bit and 8-bit I/O addresses can be used.
Z180 Internal Input/Output Registers Addresses 00-3F
The internal registers for the I/O devices built into to the Z180 processor
occupy the first 40 (hex) addresses of the I/O space. These addresses are
listed in Table C-2.
