R/W

Bit Bit Name Initial Value Slave Host Description

0 LSCIE 0 R/W — LSCI output Enable

Controls LSCI output in combination with the LSCIB

bit in HICR1. LSCI pin output is open-drain, and an

external pull-up resistor is needed to pull the output

up to V

When the LSCI output function is used, the DDR bit

for PB1 must not be set to 1.

LSCIE LSCIB

0 x: LSCI output disabled, other function of

pin is enabled

1 0: LSCI output enabled, LSCI pin output

goes to 0 level

1 1: LSCI output enabled, LSCI pin output is

high-impedance
