26.5.2.30 System Memory Access Time-Out Register (SYMATOR)
Table 26-35. CIFRR Field Descriptions
Field Description
MIF Module Interrupt Flag — This flag is set if there is at least one interrupt source that has its interrupt flag
asserted.
0 No interrupt source has its interrupt flag asserted.
1 At least one interrupt source has its interrupt flag asserted.
PRIF Protocol Interrupt Flag — This flag is set if at least one of the individual protocol interrupt flags in the Protocol
Interrupt Flag Register 0 (PIFR0) or Protocol Interrupt Flag Register 1 (PIFR1) is equal to 1.
0 All individual protocol interrupt flags are equal to 0.
1 At least one of the individual protocol interrupt flags is equal to 1.
CHIF CHI Interrupt Flag — This flag is set if at least one of the individual CHI error flags in the CHI Error Flag Register
(CHIERFR) is equal to 1.
0 All CHI error flags are equal to 0.
1 At least one CHI error flag is equal to 1.
WUPIF Wakeup Interrupt Flag — Provides the same value as GIFER[WUPIF].
FAFBIF Receive FIFO Channel B Almost Full Interrupt Flag — Provides the same value as GIFER[FAFBIF].
FAFAIF Receive FIFO Channel A Almost Full Interrupt Flag — Provides the same value as GIFER[FAFAIF].
RBIF Receive Message Buffer Interrupt Flag — This flag is set if for at least one of the individual receive message
buffers (MBCCSRn[MTD] = 0) the interrupt flag MBIF in the corresponding Message Buffer Configuration,
Control, Status Registers (MBCCSRn) is equal to 1.
0 None of the individual receive message buffers has the MBIF flag asserted.
1 At least one individual receive message buffers has the MBIF flag asserted.
TBIF Transmit Message Buffer Interrupt Flag — This flag is set if for at least one of the individual single or double
transmit message buffers (MBCCSRn[MTD] = 1) the interrupt flag MBIF in the corresponding Message Buffer
Configuration, Control, Status Registers (MBCCSRn) is equal to 1.
0 None of the individual transmit message buffers has the MBIF flag asserted.
1 At least one individual transmit message buffers has the MBIF flag asserted.

Field Description
TIMEOUT System Memory Access Time-Out — This value defines the maximum amount of time to finish a system bus
access in order to ensure correct frame transmission and reception (see Section 26.6.19.2, System Bus Access
Timeout).
