25.5.5.2 GIOLVLCLR Register
The GIOLVLCLR register is used to configure an interrupt as a low-level interrupt going to the VIM. An
interrupt can be configured as a low-level interrupt by writing a 1 into the corresponding bit of the
GIOLVLCLR register. Writing a 0 has no effect. Figure 25-11 and Table 25-8 describe this register.

Table 25-8. GIO Interrupt Priority Register (GIOLVLCLR) Field Descriptions
Bit Field Value Description
31-24 GIOLVLCLR 3 GIO low-priority interrupt for pins GIOD[7:0]
0 Read: The interrupt is a low-level interrupt.
Write: Writing a 0 to this bit has no effect.
1 Read: The interrupt is set as a high-level interrupt. The high-level interrupts are recorded to
GIOOFF1 and GIOEMU1.
Write: Sets the interrupt as a low-level interrupt. The low-level interrupts are recorded to
GIOOFF2 and GIOEMU2.
23-16 GIOLVLCLR 2 GIO low-priority interrupt for pins GIOC[7:0]
0 Read: The interrupt is a low-level interrupt.
Write: Writing a 0 to this bit has no effect.
1 Read: The interrupt is set as a high-level interrupt. The high-level interrupts are recorded to
GIOOFF1 and GIOEMU1.
Write: Sets the interrupt as a low-level interrupt. The low-level interrupts are recorded to
GIOOFF2 and GIOEMU2.
15-8 GIOLVLCLR 1 GIO low-priority interrupt for pins GIOB[7:0]
0 Read: The interrupt is a low-level interrupt.
Write: Writing a 0 to this bit has no effect.
1 Read: The interrupt is set as a high-level interrupt. The high-level interrupts are recorded to
GIOOFF1 and GIOEMU1.
Write: Sets the interrupt as a low-level interrupt. The low-level interrupts are recorded to
GIOOFF2 and GIOEMU2.
7-0 GIOLVLCLR 0 GIO low-priority interrupt for pins GIOA[7:0]
0 Read: The interrupt is a low-level interrupt.
Write: Writing a 0 to this bit has no effect.
1 Read: The interrupt is set as a high-level interrupt. The high-level interrupts are recorded to
GIOOFF1 and GIOEMU1.
Write: Sets the interrupt as a low-level interrupt. The low-level interrupts are recorded to
GIOOFF2 and GIOEMU2.
