Non-maskable
interrupt
Non-maskable interrupt request pin
Fix to high or low level when not in
use.
Interrupt requests Maskable interrupt request pin
3 to 0
Selectable as level input or edge
input. The rising edge, falling edge,
and both edges are selectable as
edges.
Interrupt request
output
Shows that an interrupt cause has
occurred. The interrupt cause can be
recognized even in the bus release
state.
Address bus
Outputs addresses. This pin is
available only on the SH7137.
Data bus
8-bit bidirectional bus. This pin is
available only on the SH7137.
Chip select 1 and Chip-select signal for external
0
memory or devices. This pin is
available only on the SH7137.
Read
Indicates reading of data from
external devices. This pin is
available only on the SH7137.
Write
Indicates a write access to bits 7 to 0
of the external data. This pin is
available only on the SH7137.
Wait
Input signal for inserting a wait cycle
into the bus cycles during access to
the external space. This pin is
available only on the SH7137.
