Detailed Description

Per-FIFO-channel register window (5 x 32-bit at +0x20 stride).

Layout matches the IPC0_0 (IPC0STA0..IPC0CLR0) block at offset 0x0C0 documented in HUM Ch 3.2.10..3.2.14 p 214-216, and is reused with offset 0x20/0x40/0x60 for IPC0_1, IPC1_0, IPC1_1 (see the IPC register address map figure on HUM p 205).
