FUNCTION
0h–Ch
P0–PC
General-Purpose Ports. These ports, P0–PC, can be used to hold intermediate calculation results,
often-used calculation coefficients, loop counter values, event counter values, comparison limit
values, etc.
Dh
PD
Module Data Port. This port is used to transfer data to and from the various functional modules in the
MAX1464. Data loaded into PD can be transferred to the data, configuration, or control register of any
of the functional modules. The data transfer is initiated using the module control port (PF). The
contents of PD are not changed during module write operations, but are overwritten by module read
operations.
Eh
PE
Module Address Port. This port is used to address a module register. A module address is loaded
into PE prior to initiating a data transfer or control function in the module control port. All modules in
the MAX1464 are accessed through this indirect addressing method. The contents of PE are not
changed by the read or write operations to module registers. Only the lower 8 bits are used. The
upper 8 bits are not decoded.
Fh
PF
Module Control Port. This port initiates an operation on the module addressed by PE. Data can be
written to, or read from, module registers. Specific bits are assigned in the module control port to
initiate operations on the MAX1464 modules:
Bit 15 (CTRL): 1 = Initiate action defined in bit 14, 0 = no action initiated. Autoreset to zero after
operation is completed.
Bit 14 (RD/
WR): 1 = read data, 0 = write data.
Bits 13–0: Not decoded.
