• Manufacturer Part Number: tmp19a61f10xbg
• Description: 32-bit Tx System Risc Tx19 Family
• Manufacturer: TOSHIBA Semiconductor CORPORATION

Note: The following must be set before the A/D conversion to guarantee accuracy in the conversion.
ADACBAS

ADAMOD0
(0xFFFF_F814)
16.1 Control Register
The A/D converter is controlled by A/D mode control registers (ADAMOD0, ADAMOD1,
ADAMOD2, ADAMOD3 and ADAMOD4). Results of A/D conversion are stored in 16 upper
and lower A/D conversion result registers ADAREG08H/L through ADAREG7FH/L. Results of
top-priority conversion are stored in ADAREGSPH/L.
Fig. 16.2 shows the registers related to the A/D converter.
