TMS370Cx0x
8-BIT MICROCONTROLLER
SPNS029C – SEPTEMBER 1995 – REVISED FEBRUARY 1997

POST OFFICE BOX 1443
HOUSTON, TEXAS 77251–1443
program EPROM
The TMS370C702 device contains 8K bytes of EPROM, mapped, at location 6000h and continuing through
location 7FFFh as shown in Figure 3. Memory addresses 7FF0h through 7FFFh are reserved for interrupt and
reset vectors. Trap vectors, used with TRAP0 through TRAP15 instructions, are located between addresses
7FC0h and 7FDFh. Reading the program EPROM modules is identical to reading other internal memory. During
programming, the EPROM is controlled by the EPROM control register (EPCTL). The program EPROM module
features include:
D Programming
In-circuit programming capability if VPP is applied to MC
Control register: EPROM programming is controlled by the EPROM control register (EPCTL) located in
the peripheral file (PF) frame at location P01Ch as shown in Table 5.
D Write protection: Writes to the program EPROM are disabled under the following conditions:
Reset halts all programming to the EPROM module.
Low-power modes
13 V not applied to MC
program ROM
The program read-only memory (ROM) consists of 8K bytes of mask-programmable ROM. The program ROM
is used for permanent storage of data or instructions. Memory addresses 7FF0h through 7FFFh are reserved
for interrupt and reset vectors. Trap vectors, used with TRAP0 through TRAP15 instructions, are located
between addresses 7FC0h and 7FDFh. Programming of the mask ROM is performed at the time of device
fabrication. Refer to Figure 3 for ROM memory map.
system reset
The system reset operation ensures an orderly start-up sequence for the TMS370Cx0x CPU-based device.
There are up to three different actions that can cause a system reset to the device. Two of these actions are
internally generated, while one (RESET pin) is controlled externally. These actions are as follows:
D External RESET pin. A low-level signal can trigger an external reset. To ensure a reset, the external signal
should be held low for one SYSCLK cycle. Signals of less than one SYSCLK can generate a reset. See the
TMS370 Family User’s Guide (literature number SPNU127) for more information.
D Watchdog (WD) timer. A watchdog-generated reset occurs if an improper value is written to the WD key
register, or if the re-initialization does not occur before the watchdog timer times out . See the
TMS370
Family User’s Guide (literature number SPNU127) for more information.
D Oscillator reset. Reset occurs when the oscillator operates outside the recommended operating range. See
the
TMS370 Family User’s Guide (literature number SPNU127) for more information.
Once a reset source is activated, the external RESET pin is driven (active) low for a minimum of eight SYSCLK
cycles. This allows the ’x0x device to reset external system components. Additionally, if a cold start (VCC is off
for several hundred milliseconds) condition or oscillator failure occurs or the RESET pin is held low, then the
reset logic holds the device in a reset state for as long as these actions are active.
After a reset, the program can check the oscillator fault flag (OSC FLT FLAG, SCCR0.4), the cold start flag
(COLD START, SCCR0.7), and the watchdog reset (WD OVRFL INT FLAG, T1CTL2.5) to determine the source
of the reset. A reset does not clear these flags. Table 6 lists the reset sources.
