Data Sheet
Applies to all input pins except analog pins RLx
Applies to all output pins except pins XLx
Wiring conditions and external circuit configuration according to
Wiring conditions and external circuit configuration according to
System interface at 16 MHz; all-ones data.
Pin leakage is measured in a test mode with all internal pullups disabled. RDO pins are not tristatable, no
leakage is measured.
Parameter not tested in production
Differential input voltage between pins RL1 and RL2; depends on programming of register LIM1.RIL(2:0)
If not specified otherwise, typical characteristics apply at
supply voltage.
