20.4.4.2
The DMACON2 register contains control bits for
controlling interrupt generation and inter-byte delay
behavior. The INTLVL<3:0> bits are used to select when
an SSP2IF interrupt should be generated. The function
of the DLYCYC<3:0> bits depends on the SPI operating
mode (Master/Slave), as well as the DLYINTEN setting.
In SPI Master mode, the DLYCYC<3:0> bits can be used

DLYCYC<3:0>: Delay Cycle Selection bits
When DLYINTEN = 0, these bits specify the additional delay (above the base overhead of the hard-
ware) in number of T
DLYINTEN = 1, these bits specify the delay in number of T
before an interrupt to the CPU is invoked. In this case, the additional delay before the SSP2BUF
register is written again is 1 T

INTLVL<3:0>: Watermark Interrupt Enable bits
These bits specify the amount of remaining data yet to be transferred (transmitted and/or received)
upon which an interrupt is generated.
1111 = Amount of remaining data to be transferred is 576 bytes
1110 = Amount of remaining data to be transferred is 512 bytes
1101 = Amount of remaining data to be transferred is 448 bytes

bytes in a transfer. By default, the hardware requires a

DLYCYC<3:0> bits may optionally be used to trigger an
additional time-out based interrupt.
