This is a bi-directional signal that connects to the CMD
signal of SD/MMC device.
This pin has an internally controlled weak pull-up
resistor.
This pin is an input signal with an internal weak pull-
down.
This pin has an internally controlled weak pull-down
resistor.
This pin may be used either as input, edge sensitive
interrupt input, or output.
This pin may be used either as input, edge sensitive
interrupt input, or output.
This pin may be used either as input, edge sensitive
interrupt input, or output.
This pin may be used either as input, edge sensitive
interrupt input, or output.
This pin has an internal weak pull-up resistor that is
enabled or disabled by the state of RESET_N.
The pull-up is enabled when RESET_N is active.
The pull-up is disabled, when the RESET_N is inactive
(some clock cycles later, after the rising edge of
RESET_N).
The state of this pin is latched internally on the rising
edge of RESET_N to determine if internal or external
program memory is used.
The state latched is stored in ROMEN bit of GPIO_IN1
register.
After the rising edge of RESET_N, this pin may be used
as GPIO6.
When this pin is left unconnected or pulled high by a
weak pull-up resistor, the USB2601/USB2602 uses the
internal ROM for program execution.
This pin may be used either as input, edge sensitive
interrupt input, or output.
This pin may be used either as input, edge sensitive
interrupt input, or output.
GPIO: This pin may be used either as input, edge
sensitive interrupt input, or output.
CRD_PWR: Card Power drive of 3.3V @ 100mA.
This pin may be used either as input, edge sensitive
interrupt input, or output.
GPIO: This pin may be used either as input, edge
sensitive interrupt input, or output.
CRD_PWR: Card Power drive of 3.3V @ 100mA.
