275 Microsecond Interrupt Configuration
The ADP5587 gives the user the flexibility of deasserting the
interrupt for 275 μs while there is a pending event. When the
INT_CFG bit in Register 0x01 is set, any attempt to clear the
interrupt bit while the interrupt pin is already asserted results
in a 275 μs deassertion. When the INT_CFG bit is cleared, the
processor interrupt remains asserted if the host tries to clear
the interrupt. This feature is particularly useful for software
development and edge triggering applications.
Debouncing
The ADP5587 has a 275 μs debounce time for GPIOs configured
as GPIs and rows in keypad scanning mode. The reset line
always has a 275 μs debounce time.
General-Purpose Outputs (GPOs)
The ADP5587 allows the user to configure all or some of its
GPIOs as GPOs. These GPOs can be used as extra enables for
the host processor or simply as trigger outputs. When configured
as an output (GPO), a digital buffer drives the pin to 0 V for a 0
and to VCC for a 1. To set any GPIO as a GPO, make sure that
the corresponding bits in Register 0x1D through Register 0x1F are
set for GPIO mode; then use Register 0x23 through Register 0x25
to set the corresponding bits for GPO mode.
Power-On Reset
For built-in power-up initialization for applications lacking a
power-on reset signal, a reset pin, RST, allows the user to reset
the registers to default values in the event of a brownout or
other reset condition.
