C164 OTP Memory Programming
2
OTP Memory Configuration
Upon reset the default memory configuration of the C164CI is determined by the state of its EA pin.
When EA is low the internal OTP memory is disabled and the startup code is fetched from external
memory.
In order to access the on-chip OTP memory after booting from external memory the internal OTP
memory must be enabled via software by setting bit ROMEN in register SYSCON. The lower 32
KBytes of the OTP memory can be mapped to segment 0 or segment 1, controlled by bit ROMS1
in register SYSCON. Mapping to segment 1 preserves the external memory containing the startup
code, while mapping to segment 0 replaces the lower 32 KBytes of the external memory with on-
chip OTP memory. In this case a valid vector table must be provided.
As the on-chip OTP memory covers more than segment 0, segmentation should be enabled (by
clearing bit SGTDIS in register SYSCON) in order to map the whole internal OTP into the address
space.
Whenever the internal memory configuration of the C164CI is changed (mapping, enabling,
disabling) the following procedure must be used to ensure correct operation:
l
Configure the internal OTP memory as required
l
Execute an inter-segment branch (JMPS, CALLS, RETS)
l
Reload all four DPP registers
Note:
Register SYSCON can only be modified
before
the execution of the EINIT instruction.
Note:
For detailed informations concerning the handling of internal non-volatile memory please refer to
the users manual, chapter System Programming“ (Handling the Internal ROM/ Pits, Traps and
Mines).
