Product specification
Microcontrollers for NTSC TVs with On-Screen
Display (OSD) and Closed Caption (CC)
P8xCx70 family
16 AFT INPUTS (ADC)
The P8xCx70 has 3 ADC channels each with 4-bit resolution. One channel is intended to measure the level of the key
pad signals. This is achieved by comparing the AFT signal with the output of a 4-bit DAC.
The compare time of the AFT is not greater than 8
μ
s at 12 MHz. Adding NOP instructions is recommended in between
the instructions which change the reference voltage or channel and the instructions which read the AFTC register bit.
Ensure that pins 9, 10 and 11 are configured as AFT functions before use (see Chapter 14).
The conversion time (T
AFC
) of an AFT (4-bit output) is calculated as shown below.
