• Registers
T2_EN (R/W)
0: Disable Timer2 interrupt
1: Interrupt CPU on falling edge of Timer 2 output
AUXDI0_INT (R/W)
0: AUXDI does not generate interrupt
1: AUXDI interrupt occurred. Write “1” to clear
T2_INT (R/W)
0: Timer 2 does not generate interrupt
1: Timer 2 interrupt occurred. Write “1” to clear
3.6 DI_FIFO: DI FIFO direct access port
The digital input FIFO data can be accessed through th is port directly.
Address: BASE + 0x10
Attribute: READ/WRITE
Data Format:
Bits 7 6 5 4 3 2 1 0
Bit # 7~0 DI_FIFO_8
Bit # 15~8 DI_FIFO_16
Bit # 31_16 DI_FIFO_32
DI_FIFO_8
Bit 7 ~ Bit 0 of digital input FIFO
DI_FIFO_16
Bit 15 ~ Bit 8 of digital input FIFO if the digital input is configured as 16-bit wide
or 32-bit wide.
DI_FIFO_32
Bit 31 ~ Bit 16 of digital input FIFO if the digital input is
configured as 32-bit wide
Note: Although this port is R/W port, write operation should be avoided in
normal operation. If both PORT A and PORT B are configured as
output ports, read/write to this port is meaningless.
