PT_INT
R
Port Transport Interrupt
This bit indicates when the serial port interrupt is
active. This condition depends on the states of the
PINT_EN and DSINT_EN bits in the Serial Port
Interrupt Mask Register.
When PINT_EN is 1, an interrupt will occur
whenever data is available in the serial port input
FIFO ("S_DAV" in the Serial Port
Configuration/Status Register is 1).
When DSINT_EN is 1, an interrupt will be active
whenever the CPU can write to the Serial Port Data
Register to transmit a byte of data.
If both PINT_EN and DSINT_EN are enabled,
the interrupt will be active if either condition is met.
7.3.7. Serial Port Interrupt Mask Register (0x0A)
(Read/Write, Default 0x00)
This register enables the serial port interrupts. The default for this register is 0x00 (interrupts disabled).
