 2015 Microchip Technology Inc. Preliminary DS60001320B-page 189
PIC32MZ Embedded Connectivity with Floating Point Unit (EF) Family
bit 4 CHAEN: Channel Automatic Enable bit
1 = Channel is continuously enabled, and not automatically disabled after a block transfer is complete
0 = Channel is disabled on block transfer complete
bit 3 Unimplemented: Read as ‘0’
bit 2 CHEDET: Channel Event Detected bit
1 = An event has been detected
0 = No events have been detected
bit 1-0 CHPRI<1:0>: Channel Priority bits
11 = Channel has priority 3 (highest)
10 = Channel has priority 2
01 = Channel has priority 1
00 = Channel has priority 0
REGISTER 10-7: DCHxCON: DMA CHANNEL x CONTROL REGISTER (CONTINUED)
Note 1: The chain selection bit takes effect when chaining is enabled (i.e., CHCHN = 1).
2: When the channel is suspended by clearing this bit, the user application should poll the CHBUSY bit (if
available on the device variant) to see when the channel is suspended, as it may take some clock cycles
to complete a current transaction before the channel is suspended.
