Input/Output Data Inversion Function; Overview - Renesas H8/38024 Hardware Manual

Pin Pin Functions and Selection Method
PB /AN /extU Switching is accomplished by combining CH3 to CH0 in AMR and VINTUSEL in
1 1
LVDCR as shown below. Note that VINTUSEL is implemented on the H8/38124
Group only.
Note: The extU pin is implemented on the H8/38124 Group only.
PB /AN /extD Switching is accomplished by combining CH3 to CH0 in AMR and VINTDSEL in
0 0
LVDCR as shown below. Note that VINTDSEL is implemented on the H8/38124
Group only.
Note: The extD pin is implemented on the H8/38124 Group only.
