data EEPROM
The TMS370Cx36 devices, containing 256 bytes of data EEPROM, have a memory mapped beginning at
location 1F00h and continuing through location 1FFFh. Writing to the data EEPROM module is controlled by
the data EEPROM control register (DEECTL) and the write-protection register (WPR). Programming algorithm
examples are available in the TMS370 Family User’s Guide(literature number SPNU127) or the
TMS370 Family Data Manual(literature number SPNS014B). The data EEPROM features include the following:
Programming:
–
Bit-, byte-, and block-write/erase modes.
–
Internal charge pump circuitry. No external EEPROM programming voltage supply is needed.
–
Control register: Data EEPROM programming is controlled by the DEECTL located in the PF frame
beginning at location P01A. See Table 5.
–
In-circuit programming capability. There is no need to remove the device to program.
Write protection. Writes to the data EEPROM are disabled during the following conditions.
–
Reset. All programming of the data EEPROM module is halted.
–
Write protection active. There is one write-protect bit per 32-byte EEPROM block.
–
Low-power mode operation
Write protection can be overridden by applying 12 V to MC.

program EPROM
The TMS370C736 device contains 16K bytes of EPROM mapped, beginning at location 4000h and continuing
through location 7FFFh as shown in Figure 3. Reading the program EPROM modules is identical to reading
other internal memory. During programming, the EPROM is controlled by the EPROM control register
(EPCTLL). The program EPROM module features include:
Programming
–
In-circuit programming capability if V
PP
is applied to MC
Control register: EPROM programming is controlled by the EPROM control register (EPCTLL) located
in the peripheral file (PF) frame at location P01C as shown in Table 5.
–
Write protection: Writes to the program EPROM are disabled under the following conditions:
–
Reset: All programming to the EPROM module is halted
–
Low-power modes
–
13 V not applied to MC
Memory addresses 7FE0h through 7FEBh are reserved for Texas Instruments (TI
), and addresses 7FECh through 7FFFh are reserved
for interrupt and reset vectors. Trap vectors, used with TRAP0 through TRAP15 instructions, are located between addresses 7FC0h and
7FDFh.
