18.3 Typical software model
Remark: SH7709’s system clock input is for reference only. Refer to SH7709’s
specification for its actual use.
The ISP1160/01 can work under either 3.3 V or 5.0 V power supply; however, its internal
core works at 3.3 V. When using 3.3 V as the power supply input, the internal DC/DC
regulator will be bypassed. It is best to connect all four power supply pins (V
V
of the ISP1160/01’s I/O pins are 5 V-tolerant. This feature allows the ISP1160/01 the
flexibility to be used in an embedded system under either a 3.3 V or a 5 V power supply.
A typical SH7709 interface circuit is shown in
This section shows a typical software requirement for an embedded system that
incorporates the ISP1160/01. The software model for a Digital Still Camera (DSC) is used
as the example for illustration (as shown in
Class driver and device driver, both of which provide API for application tasks for host
function.

HOLD1
There is a DMA channel standard control line: DREQ and DACK_N. The DREQ signal
has programmable active levels.
An interrupt line INT is used by the HC. It has programmable level/edge and polarity
(active HIGH or LOW).
The internal 15 kΩ pull-down resistors are used for the HC’s two USB downstream
ports.
The RESET_N signal is active LOW.
