36 / 61 page  R8C/36T-A Group 4. Electrical Characteristics R01DS0055EJ0100 Rev.1.00 Page 36 of 58 Dec 09, 2011 4.3 Peripheral Function Characteristics Notes: 1. If the CPU and the flash memory stop, the A/D conversion result will be undefined. 2. When the analog input voltage exceeds the reference voltage, the A/D conversion result will be 3FFh in 10-bit mode and FFh in 8-bit mode. Note: 1. When the digital filter is not selected.
