Prototype
bool R_INTC_Modify(
uint16_t data1,
// Register selection
uint8_t data2,
// Logical operation
uint8_t data3
// Modification value
);
Description
Update the value in an interrupt register.
[data1]
•
The register to be updated.
PDL_INTC_REG_IR_(register) or
PDL_INTC_REG_IER_(register) or
PDL_INTC_REG_IPR_(register)
Select the Interrupt Request register or
Interrupt Request Enable register or
Interrupt Priority register
[data2]
•
The logical operation to be applied to the register contents.
PDL_INTC_AND or
PDL_INTC_OR or
PDL_INTC_XOR
Select between AND (&), OR (|) or Exclusive-OR (^).
[data3]

Remarks
•
This function uses an interrupt routine to modify the IPL bits. If the user has disabled interrupts
(cleared the ‘I’ bit in the PSW register) in their own code, this function will lock up.
•
For (register), select one of the registers listed in the tables starting on page 4-20.
