INTE:
INTC[6:0]:
FIFO is empty. The set point is decimal 128 when the INTC[6:0] is all ‘Zero’s.

Default
Bit No.
Type
Selection of the RHDLC block (#1 or #2) whose registers are visible on the microprocessor interface is done via the RHDLCSEL[1:0] (b7~6, T1/
= 0: Disable the interrupt on the INT pin when there is a transition from ‘0’ to ‘1’ on the INTR (b0, T1/J1-056H).
= 1: Enable the interrupt on the INT pin when there is a transition from ‘0’ to ‘1’ on the INTR (b0, T1/J1-056H).
These bits set the interrupt set point of the FIFO buffer. Exceeding the set point will introduce an interrupt, and the interrupt will persist until the
The contents of this register should only be changed when the EN (b0, T1/J1-054H) is logic 0. This prevents any erroneous interrupt generation.
