HT48R064G/065G/066G/0662G
Enhanced I/O Type 8-Bit OTP MCU with OPA
Configuration Options
Configuration options refer to certain options within the MCU that are programmed into the OTP
Program Memory device during the programming process. During the development process, these
options are selected using the HT-IDE software development tools. As these options are programmed
into the device using the hardware programming tools, once they are selected they cannot be changed
later by the application software. All options must be defined for proper system function, the details of
which are shown in the table.
No.
Options
1
Watchdog Timer: enable or disable
2
Watchdog Timer clock source: LXT, LIRC or fSYS/4
Note: LXT oscillator must be selected by OSC configuration option if WDT clock source is from LXT.
