Pinout Information
Pin Descriptions
PORTA5
202
I/O U5
General-purpose I/O port bit controlled by PADAT5 and PAEN5. This pin
has other possible functions depending on the IREN, EIEN registers.
• When EIEN=1 and PAEN5=1, this pin can function as an external
interrupt to the on-chip CPU.
• When IREN=1 and PAEN5=1, this pin can function as an input to the on-
chip IR receiver 1. (IRRCVR1). .
PORTA6
201
I/O U5
General-purpose I/O port bit controlled by PADAT6 and PAEN6. This pin
can also function as BLKSPL when BLKSMPLEN=1.
• When BLKSMPLEN=1 and PAEN6=0, PORTA6 is GPORT black sample
clamp pulse output (typically used as port of an external DC restoration
circuit) (BLKSPL) This pin has one other possible function when
PREF1EN=1.
• When PREF1EN=1 and PAEN6=0, PORTA6 is a variable duty-cycle
pulse reference generator (PWM) output controlled by PREF1HI and
PREF1LO.
PORTA7
200
I/O D5
General-purpose I/O port bit controlled by PADAT7 and PAEN7. This pin
has one other possible function when PREF0EN=1.
When PREF0EN=1 and PAEN7=0, PORTA7 is a variable duty-cycle pulse
reference generator (PWM) output controlled by PREF0HI and PREF0LO.
PORTB0
57
I/O D5
General purpose I/O port bit controlled by PBDAT0 and PBEN0. PORTB0
can also function as GRO0 when in 48 bit graphics input mode; VR0 when
in 24 bit RGB video input mode; Y0 when in 24 bit YUV video input mode.
PORTB1
58
I/O D5
General purpose I/O port bit controlled by PBDAT1 and PBEN1. PORTB1
can also function as GRO1 when in 48 bit graphics input mode; VR1 when
in 24 bit RGB video input mode; Y1 when in 24 bit YUV video input mode.
PORTB2
59
I/O D5
General purpose I/O port bit controlled by PBDAT2 and PBEN2. PORTB2
can also function as:
PORTB3
60
I/O D5
General purpose I/O port bit controlled by PBDAT3 and PBEN3. PORTB3
can also function as:
