SYSCR2 controls the functions of port 6 and the functions of some pins in port 9.
SYSCR2 is initialized to H'80 by a reset and in the hardware standby mode. It is not initialized in
the software standby mode.
Bit 7—Reserved: This bit cannot be modified and is always read as 1.
Bit 6—Interrupt Request 5 Enable (IRQ5E): Selects the function of pin P63.
Bit 6
IRQ5E
0
1
Description
P63 functions as an input/output pin (but as the PW3 output pin
(Initial value)
if P6PWME and the OE bit of PWM timer 3 are both set to 1).
P63 is the IRQ5 input pin regardless of the value of P63DDR (although the logic level
of the pin can still be read).
Bit 5—Interrupt Request 4 Enable (IRQ4E): Selects the function of pin P62.
Bit 5
IRQ4E
0
1
Description
P62 functions as an input/output pin (but as the PW2 output
(Initial value)
pin if P6PWME and the OE bit of PWM timer 2 are both set to 1).
P62 is the IRQ4 input pin regardless of the value of P62DDR (although the logic level
of the pin can still be read).
Bit 4—Interrupt Request 3 Enable (IRQ3E): Selects the function of pin P61.
Bit 4
IRQ3E
0
1
Description
P61 functions as an input/output pin (but as the PW1 output
(Initial value)
pin if P6PWME and the OE bit of PWM timer 1 are both set to 1).
P61 is the IRQ3 input pin regardless of the value of P61DDR (although the logic level
of the pin can still be read).
Bit 3—Interrupt Request 2 Enable (IRQ2E): Selects the function of pin P60.
Bit 3
IRQ2E
0
1
Description
P60 functions as an input/output pin.
(Initial value)
P60 is the IRQ2 input pin regardless of the value of P60DDR (although the logic level
of the pin can still be read).
