Tool/software:
I congfig TI PMBUS as slave mode.
When PMBUS master sends an address that does not match slave address, I want to know:
1. Will PMBSTS.SLAVE_ADDR_READY of PMBUS slave be set to 1？
2. Will PMBHSA of PMBUS slave updated to indicate the address sent by master？
Beside the first two questions , I have another two question:
3.Can PMBUS handle General call address/START byte/CBUS address in I2C protocol？（Described in the figure）
4.What is the difference in the behavior of PMBUS during the period when PMBCTRL.i2cmode is set to 0 and 1? When should I config this bit if I want to use TI PMBUS as a slave equipment.
Please reply to me ASAP. Thanks.
1. “Please see the PMBus academy chapter and linked collateral (namely the Introduction to PMBus document) and let me know if it answers your other questions.”
--I cannot access PMBus academy chapter . Can you answer me directly?
2. Actually I did some test on your launch broad
I use I2C(master) to sent general call (addr:0000000+W)/Start Byte(addr:0000000+R) to PMBUS(slave)
I config the PMBSC.RX_BYTE_ACK_CNT=3 MAN_CMD=0 MAN_SLAVE_ACK=0 SLAVE_ADDR=0x3C.
a. General Call
I found PMBUS can ack at every acknowledge bit but PMBRXBUF and PMBSTS does not have any updated as PMBUS is not matched anymore.
--What this means? Can PMBUS handle General Call ? Why PMBUS can ack but cannot receive any data?
b. Start Byte
PMBUS not ack at acknowledge bit and PMBSHA does not updated anymore. Just like never be matched.
--What this means? Can PMBUS handle Start Byte？
