MC68HC11EA9
MC68HC11EA9TS/D
RESET:
* Same level as an instruction
Refer to 9 Analog-to-Digital Converter
Refer to 4.10 EEPROM.
Always reads zero
Refer to the following table of COP timer rates.
* Can be written only once in first 64 cycles after reset in normal modes, or at any time in special modes.
0 = IRQ input is active-low
1 = IRQ input recognizes falling edges only
0 = No stabilization delay on exit from STOP mode.
1 = A delay of approximately 4000 E-clock cycles is imposed as the MCU exits STOP mode.
0 = Clock monitor disabled; slow clock can be used.
1 = Slow or stopped clocks cause COP failure reset.
