In MPC mode, an MPC bit is added between the MSB bit (D7) of serial data and the parity bit (P), indicating
that this 8 bit data is address information if MPC = “1”, and that it is data itself if MPC = “0”. Therefore, unlike
normal mode, A-D pin control is unnecessary. (Connect the A-D pin to GND.)
Except for an MPC bit that is added to serial data, everything, including timing, is the same as in normal mode.
In UART, transmit/receive is controlled by the shift clock with a 1/64 source oscillation frequency. If UART is
used, set the baud rate at the CPU side.
SCLK/PAE pin: “H” selects parity yes, “L” selects parity no.

Note:
If an abnormality occurs at the host CPU serial interface part (missing bit, synchronization shift, etc.),
reset the MSM6636 from the CPU to initialize the interface circuit, then start communication again.
Even if the MSM6636 is reset, an internal register like a physical address is not initialized, therefore
resetting is unnecessary. (See Status at Reset in “Internal Register Details” (page 3-1).)
Normal/abnormal of the host CPU interface part can be evaluated by sending an RD request for the
physical address value and checking whether the set physical address value can be correctly read.
