3.4.9.3 Input Port Interrupt Enable (PIOIEN) R/W
The PIOIEN bit enables the interrupt input bit on the input port. The input is edge triggered. The polarity is selected
by the IPINTPOL bit. The status and clear bit for this interrupt is PIOINTSTAT, in the AMINTCLR register.
PIOIEN
Function
0
Disable interrupt input
1
Enable interrupt input
3.4.9.4 Timer Count Interrupt Enable (TCNTINTEN) R/W
The TCNTINTEN bit enables an interrupt that occurs when the timer count reaches zero. The status and clear bit for
this interrupt is TCNTINTSTAT, in the AMINTCLR register.
TCNTINTEN
Function
0
Disable timer interrupt
1
Enable timer interrupt
3.4.9.5 Vertical Blank Interrupt Enable (VBLANKINTEN) R/W
The VBLANKINTEN bit enables an interrupt that occurs when the PWG vertical blank signal goes low, indicating
the start of the PWG vertical blank region defined by the VOFF and VACT register values. The status and clear bit for
this interrupt is VBLANKINTSTAT, in the AMINTCLR register.
VBLANKINTEN
Function
0
Disable PWG Vertical Blank interrupt
1
Enable PWG Vertical Blank interrupt
3.4.9.6 Vertical Blank Even Field Interrupt Enable (VBEVENINTEN) R/W
The VBEVENINTEN bit enables an interrupt that occurs when the PWG vertical blank signal goes low, and the
PWG field signal is low. The field signal low indicates an even field. Vertical blank going low indicates the start of
the PWG vertical blank region defined by the VOFF and VACT register values. The status and clear bit for this inter-
rupt is VBEVENINTSTAT, in the AMINTCLR register.
VBEVENINTEN
Function
0
Disable PWG Vertical Blank Even Field interrupt
1
Enable PWG Vertical Blank Even Field interrupt
3.4.9.7 Vertical Blank Odd Field Interrupt Enable (VBODDINTEN) R/W
The VBODDINTEN bit enables an interrupt that occurs when the PWG vertical blank signal goes low, and the PWG
field signal is high. The field signal high indicates an odd field. Vertical blank going low indicates the start of the
PWG vertical blank region defined by the VOFF and VACT register values. The status and clear bit for this interrupt
is VBODDINTSTAT, in the AMINTCLR register.
VBEVENINTEN
Function
0
Disable PWG vertical blank odd field interrupt
1
Enable PWG vertical blank odd field interrupt
