0 = PSoC block is not the end of a chained function (End should not be set to 0 in block DCA07)
1 = PSoC block is the end of a chained function, or is an unchained PSoC block
Bit 4
:
Mode 1
The definition of the Mode [1] bit depends on the block function selected
Timer: The Mode [1] bit signifies the Compare Type
0 = Less Than or Equal
1 = Less Than
Counter: The Mode [1] bit signifies the Compare Type
0 = Less Than or Equal
1 = Less Than
CRC/PRS: The Mode [1] bit is unused in this function
Deadband: The Mode [1] bit is unused in this function
UART: The Mode[1] bit signifies the Interrupt Type (Transmitter only)
0 = Transmit: Interrupt on TX_Reg Empty
1 = Transmit: Interrupt on TX Complete
SPI: The Mode[1] bit signifies the Interrupt Type
0 = Master: Interrupt on TX Reg Empty, Slave: Interrupt on RX Reg Full
1 = Master: Interrupt on SPI Complete, Slave: Interrupt on SPI Complete
Bit 3
:
Mode 0
The definition of the Mode [0] bit depends on the block function selected
Timer: The Mode [0] bit signifies Interrupt Type
0 = Terminal Count
1 = Compare True
Counter: The Mode [0] bit signifies Interrupt Type
0 = Terminal Count
1 = Compare True
CRC/PRS: The Mode [0] bit is unused in this function
Deadband: The Mode [0] bit is unused in this function
UART: The Mode [0] bit signifies the Direction
0 = Receive
1 = Transmit
