[Bit 7] EIR1: External-interrupt request flag
When the edge specified by the SL11 and SL10 bits is input to the INT1
pin, bit 7 is set to 1. When the EIE1 bit is 1, an interrupt request (IRQ1) is
output if this bit is set.
The meaning of each bit to be read is as follows:
1 is always read when the Read Modify Write instruction is read.
The meaning of each bit to be written is as follows:
[Bits 6 and 5] SL11 and SL10: Edge-polarity mode select bits
These bits are used to control the input edge polarity mode of the INT1 pin.
[Bit 4] EIE1: Interrupt-enable bit
This bit is used to enable an external-interrupt request by the INT1 pin.
[Bit 3] EIR0: External-interrupt request flag
When the edge specified by the SL01 and SL00 bits is input to the INT0
pin, bit 3 is set to 1. When the EIE0 is 1, an interrupt request (IRQ0) is
output if this bit is set.
The meaning of each bit to be read is as follows:
1 is always read when the Read Modify Write instruction is read.
The meaning of each bit to be written is as follows:
