Description
ADR input — sets the least-significant I
address bit of the ISP1301; latched-on reset
(including power-on reset)
PSW output — enables or disables the external
charge pump after reset
bidirectional; push-pull input; 3-state output
serial I
bidirectional; push-pull input; open-drain output
serial I
bidirectional; push-pull input; open-drain output
asynchronous reset; active LOW
push-pull input
interrupt output; active LOW
open-drain output
speed selection input for the ATX; effective when
bit SPD_SUSP_CTRL = 0:
push-pull input
output of the internal voltage regulator; an external
decoupling capacitor of 0.1 F is required
suspend selection input for the ATX; effective when
bit SPD_SUSP_CTRL = 0:
push-pull input
OE_N input — enables driving DP and DM when in
USB mode
INT_N output — interrupt (push pull) when
suspended and bit OE_INT_EN = 1
bidirectional; push-pull input; 3-state output
single-ended DM receiver output
push-pull output
single-ended DP receiver output
push-pull output
differential receiver output; reflects the differential
value of DP and DM
push-pull output
SE0 (input and output) — SE0 functions in
DAT_SE0 USB mode
VM (input and output) — VM functions in VP_VM
USB mode
bidirectional; push-pull input; 3-state output
