LPC84x
32-bit Arm Cortex-M0+ microcontroller
14.6 Pin states in different power modes
[1] Default and programmed pin states are retained in sleep, deep-sleep, and power-down modes.
Table 35. Pin states in different power modes
Pin Active Sleep Deep-sleep/power-
down
Deep power-down
PIOn_m pins (not
I2C)
As configured in the IOCON
[1]
. Default: internal pull-up
enabled.
Floating.
Open-drain
I2C-bus pins
As configured in the IOCON
[1]
. Floating.
RESET
Reset function enabled. Default: input, internal pull-up
enabled.
Reset function disabled; floating; if the part
is in deep power-down mode, the RESET
pin needs an external pull-up to reduce
power consumption.
WAKEUP
As configured in the IOCON
[1]
. WAKEUP function inactive. Wake-up function enabled; can be disabled
by software.
