HMc Mode - Serial Port rEaD operation
A typical HMC Mode READ cycle is shown in Figure 37.
a. The Master (host) asserts both sEN (serial Port Enable) and sDI to indicate a READ cycle, followed
by a rising edge sCLK. Note: The Lock Detect (LD) function is usually multiplexed onto the LD_sDO
pin. It is suggested that LD only be considered valid when sEN is low. In fact LD will not toggle until
the first active data bit toggles on LD_sDO, and will be restored immediately after the trailing edge
of the LsB of serial data out as shown in Figure 37.
b. The slave (PLL) reads sDI on the 1st rising edge of sCLK after sEN. sDI high initiates the READ
cycle (RD)
c. Host places the six address bits on the next six falling edges of sCLK, MsB first.
d. slave registers the address bits on the next six rising edges of sCLK (2-7).
e. slave switches from Lock Detect and places the requested 24 data bits on sD_LDO on the next 24
rising edges of sCK (8-31), MsB first .
f.
Host registers the data bits on the next 24 falling edges of sCK (8-31).
g. slave restores Lock Detect on the 32nd rising edge of sCK.
h. sEN is de-asserted on the 32nd falling edge of sCLK.
i.
The 32nd falling edge of sCLK completes the READ cycle.
