• Selection of 8 counter input clocks for each channel
• The following operations can be set for each channel:
• Buffer operation settable for channel 0
• Phase counting mode settable independently for each of channels 1 and 2
• Cascaded operation
• Fast access via internal 16-bit bus
• 13 interrupt sources
• Automatic transfer of register data
• A/D conversion start trigger can be generated
• Module stop mode can be set
