Description
Data Interrupt Status Flag
This status flag indicates that the module has data to be
read or requires data to be written.
In either case this bit is set to 1 regardless of the value
of the DIEN bit to allow polling.
The interrupt can be masked by clearing DIEN, but
cannot be cleared by writing to this bit.
If DIRQ= 1 and DIEN = 1, an interrupt occurs.
•
0: No unread data in SSIRDR
1: Unread data in SSIRDR
•
0: Transmit buffer is full.
1: Transmit buffer is empty and requires data to be
Reserved
The read value is undefined. The write value should
always be 0.
Channel Number
These bits show the current channel number.

written to SSITDR.
TRMD = 0 (Receive mode)
TRMD = 1 (Transmit mode)
TRMD = 0 (Receive mode)
CHNO indicates which channel the data in SSIRDR
currently represents. This value will change as the
data in SSIRDR is updated from the shift register.
TRMD = 1 (Transmit mode)
CHNO indicates which channel is required to be
written to SSITDR. This value will change as the
data is copied to the shift register, regardless of
whether the data is written to SSITDR.
