AP160 AMICC [AMIC Technology], AP160 Datasheet - Page 16

• Manufacturer Part Number: AP160
• Description: 8-BIT MICROCONTROLLER WITH 8KB OTP
• Manufacturer: AMICC [AMIC Technology]

PROGRAM MEMORY LOCK BITS
The AP160 has three lock bits that can be left unprogrammed(U) or can be programmed (P) to obtain the additional
features listed in the following table.
OSCILLATOR CHARACTERISTICS
XTAL1 and XTAL2 are the input and output, respectively, of an inverting amplifier. The pins can be configured for use as an
on-chip oscillator, as shown in the logic symbol. To drive the device from an external clock source, XTAL1 should be driven
while XTAL2 is left unconnected. There are no requirements on the duty cycle of the external clock signal, because the
input to the internal clock circuitry is through a divide-by-two flip-flop. However, minimum and maximum high and low times
specified in the data sheet must be observed.

No program lock features
MOVC instructions executed from external program memory are disabled from fetching
code bytes from internal memory, EA is sampled and latched on reset, and further
programming of the OPT EPROM is disabled.
Same as mode 2, but verify is also disabled.
Same as mode 3, bur external execution is also disabled.
