This section describes in blocks the functions and basic opera-
tions of the TMP96C031F device.
Check the chapter Guidelines and Restrictions for proper
care of the device.
Operation
3.1 CPU
The TMP96C031F device has a built-in high-performance 16-
bit CPU. (For CPU operation, see TLCS-900 CPU in the book
Core Manual Architecture User Manual.)
This section describes CPU functions unique to
TMP96C031F that are not described in the previous section.
3.1.1 Reset
To reset the TMP96C031F, the RESET input must be kept at 0
for at least 10 system clocks (10 states: 1
system clock) within an operating voltage range and with a sta-
ble oscillation.
When reset is accepted, the CPU sets as follows:
Program counter (PC) to 8000H.
Stack pointer (XSP) for system mode to 100H.
SYSM bit of status register (SR) to 1. (Sets to system mode.)
IFF2 to 0 bits of status register to 111. (Sets mask register to
interrupt level 7.)
MAX bit of status register to 0. (Sets to minimum mode.)
Bits RFP2 to 0 of status register to 000. (Sets register banks
to 0.)
μ
s with a 20MHz
When reset is released, instruction execution starts from
address 8000H. CPU internal registers other than the above
are not changed.
When reset is accepted, processing for built-in I/Os,
ports, and other pins is as follows:
Initializes built-in I/O registers as per specifications.
Sets port pins (including pins also used as built-in I/Os) to
general-purpose input/output port mode (sets I/O ports to
input ports).
Sets the WDTOUT pin to 0. (Watchdog timer is set to enable
after reset.)
Pulls up the CLK pin to 1.
Sets the ALE pin to 0.
3.1.2 External Data Bus Width Selection Pin (AM8/16)
The TMP96C031F automatically operates in 8-bit bus/16-bit
bus mode after reset depending on how the AM8/16 pin is set.
The TMP96C031F have altogether the following 23 inter-
rupt sources:
For mixed external 8/16-bit data bus or fixed 16-bit data bus
Set this pin to “0”. Then the AD8 to 15/A8 to 15 pins are
fixed to functions AD8 to 15.
The external data bus width is set by the chip select/wait
control register described in section 3.6.1.
For fixed external 8-bit data bus
Set this pin to “1”. Then the AD8 to 15/A8 to 15 pins are
fixed to functions A8 to 15.
The value of chip select/wait control register bit 4
(<B0BUS>, <B1BUS>, <B2BUS>, <B3BUS>) described in
Section 3.6.1 is ignored and the bus is fixed external 8-bit data
bus.
