supply . The chip will not operate if any V
is left unconnected.
Ground: Connected to ground. Connect all V
pins to the system ground. The chip will not
operate if any V
PROM programming power supply: Connected
to the power supply (V
operation. Apply +12.5 V when programming
the PROM in the SH7034 (PROM version).
External clock: Connected to a crystal
resonator or external clock input having the
same frequency as the system clock (CK).
Crystal: Connected to a crystal resonator with
the same frequency as the system clock (CK).
If an external clock is input at the EXTAL pin,
leave XTAL open.
System clock: Supplies the system clock (CK)
to peripheral devices.
Reset: Low input causes a power-on reset if
NMI is high, or a manual reset if NMI is low.
Watchdog timer overflow: Overflow output
signal from the watchdog timer.
Bus request: Driven low by an external device
to request bus ownership.
Bus request acknowledge: Indicates that bus
ownership has been granted to an external
device. By receiving the BACK signal, a device
that has sent a BREQ signal can confirm that it
has been granted the bus.
