6.6 Serial Port
The W921E400A/W921C400 has a clock-synchronous serial interface which transmits and receives
8-bit data as default. User can program the P6IO register to select port P6 as the serial port.
The serial transmitter/receiver function can be operated with multi-nibble function and the LSB of
every nibble is transmitted/received first.
The serial transmitted/received data are come from or are stored into the serial buffer registers
(address 050H to 14EH); how many nibbles will be transmitted/received is decided by the serial MSB
nibble register (SRMNR, address = 0AH) and serial LSB nibble register (SRLNR, address = 09H).
SRMNR REG: (ADDRESS = 00AH, default data = 0H)

SRLNR REG: (ADDRESS = 009H, default data = 2H)
The transceiver data will be latched on the rising or falling edge of the clock; this is determined by the
serial clock inverter control register (SRINV, address = 00CH). Before SOP or SIP instruction is
executed the SRINV register must be set to the exact value. Once the bit3 and bit2 of SRINV register
are both cleared to zero, the serial transceiver function will be reset to initial status immediately.
