20.3.1.40 LFS Interrupt Flag Register (LFSFLAG)
Figure 20-58. LFS Interrupt Flag Register (LFSFLAG) [offset = 12Ch]
31 0
LFSI[31:0]
R/WP-0
LEGEND: R/W = Read/Write; WP = Write in privilege mode only; -n = value after reset
Table 20-46. LFS Interrupt Flag Register (LFSFLAG) Field Descriptions
Bit Field Value Description
31-0 LFSI[n] Last frame started (LFS) flags. Bit 0 corresponds to channel 0, bit 1 corresponds to channel 1, and so
on.
Note: Reading from the respective interrupt channel offset register also clears the
corresponding flag (see Section 20.3.1.45 and Section 20.3.1.50 ).
Note: The state of the flag bit can be polled even if the corresponding interrupt enable bit is
cleared.
0 Read: LFS interrupt of the corresponding channel is not pending.
Write: No effect.
1 Read: LFS interrupt of the corresponding channel is pending.
Write: The flag is cleared.
20.3.1.41 HBC Interrupt Flag Register (HBCFLAG)
Figure 20-59. HBC Interrupt Flag Register (HBCFLAG) [offset = 134h]
31 0
HBCI[31:0]
R/WP-0
LEGEND: R/W = Read/Write; WP = Write in privilege mode only; -n = value after reset
Table 20-47. HBC Interrupt Flag Register (HBCFLAG) Field Descriptions
Bit Field Value Description
31-0 HBCI[n] Half block transfer (HBC) complete flags. Bit 0 corresponds to channel 0, bit 1 corresponds to channel
1, and so on.
Note: Reading from the respective interrupt channel offset register also clears the
corresponding flag (see Section 20.3.1.46and Section 20.3.1.51).
Note: The state of the flag bit can be polled even if the corresponding interrupt enable bit is
cleared.
0 Read: HBC interrupt of the corresponding channel is not pending.
Write: No effect.
1 Read: HBC interrupt of the corresponding channel is pending.
Write: The flag is cleared.
