HICR0 Bit 1—LSMI Output Enable (LSMIE)
HICR1 Bit 1—LSMI Output Bit (LSMIB)
These bits control LSMI output. LSMI pin output is open-drain, and an external pull-up resistor is
needed to pull the output up to V_CC.
When the LSMI output function is used, the DDR bit for PB0 must not be set to 1.

Description
LSMI output disabled, other function of pin PB0 is enabled
LSMI output disabled, other function of pin PB0 is enabled
LSMI output enabled, LSMI pin output goes to 0 level
LSMI output enabled, LSMI pin output is high-impedance
(Initial value)
HICR0 Bit 0—LSCI Output Enable (LSCIE)
HICR1 Bit 0—LSCI Output Bit (LSCIB)
These bits control LSCI output. LSCI pin output is open-drain, and an external pull-up resistor is
needed to pull the output up to V_CC.
When the LSCI output function is used, the DDR bit for PB1 must not be set to 1.
