AFE7906: I would like to set ALARM1 and ALARM2 of AFE7906 as below using AFE79XX tool.

I would like to set ALARM1 and ALARM2 of AFE7906 as below using AFE79XX tool.

ALARM1　：
　　　　enable SerDes PLL unlock
　　　　enable RX digital chain FIFO overflow
　　　　enable FB digital chain FIFO overflow
　　　　disable Macro Complete
　　　　enable Macro error
　　　　enable Input Signal Error

ALARM2　：
　　　　disable SerDes PLL unlock
　　　　disable RX digital chain FIFO overflow
　　　　disable FB digital chain FIFO overflow
　　　　enable Macro Complete
　　　　disable Macro error
　　　　disable Input Signal Error

How should I write the python file?

    Hi Suematsu,

    You can disable the different alarm groups per alarm pin and assign the alarm pins to the desired GPIOs like in the code below.

    ##Alarm1##
sysParams.intPinsParams[0]['JESD'] = True
sysParams.intPinsParams[0]['SPI'] = True
sysParams.intPinsParams[0]['PLL'] = True
sysParams.intPinsParams[0]['TXAPAP'] = True
sysParams.intPinsParams[0]['TXBPAP'] = True
sysParams.intPinsParams[0]['TXCPAP'] = True
sysParams.intPinsParams[0]['TXDPAP'] = True

##Alarm2##
sysParams.intPinsParams[1]['JESD'] = True
sysParams.intPinsParams[1]['SPI'] = True
sysParams.intPinsParams[1]['PLL'] = True
sysParams.intPinsParams[1]['TXAPAP'] = True
sysParams.intPinsParams[1]['TXBPAP'] = True
sysParams.intPinsParams[1]['TXCPAP'] = True
sysParams.intPinsParams[1]['TXDPAP'] = True


##############		GPIO		##############
sysParams.gpioMapping	= {
						'H8': 'ADC_SYNC0',
						'H7': 'ADC_SYNC1',
						'N8': 'ADC_SYNC2',
						'N7': 'ADC_SYNC3',
						'H9': 'DAC_SYNC0',
						'G9': 'DAC_SYNC1',
						'N9': 'DAC_SYNC2',
						'P9': 'DAC_SYNC3',
						'P14': 'GLOBAL_PDN',
						'K14': 'FBABTDD',
						'R6': 'FBCDTDD',
						'H15': ['TXATDD','TXBTDD'],
						'V5': ['TXCTDD','TXDTDD'],
						'E7': ['RXATDD','RXBTDD'],
						'R15': ['RXCTDD','RXDTDD'],
						"N16": "ALARM1",
						"N15": "ALARM2"
						}

    I will reach out to the software team on if there is a way to disable only certain features within the SPI block for one of the alarm pins only like your requested mode. Since both Macro error and Macro complete are part of the SPI block.

    Best,

    Camilo
