Bits 7~0 (DA7~DA0): When the MCU is used as Slave device for I

2C application, this

bus to extract the message delivered to the MCU.

NOTE

Slave Address 0x77 is reserved for WTR use.

Bit 7 (CES):

Clock Edge Select bit

0: Data shift out on a rising edge, and shift in on a falling edge. Data is on

hold during a low-level.

1: Data shift out on a falling edge, and shift in on a rising edge. Data is on

hold during a high-level.

Bit 6 (SPIE): SPI Enable bit

0: Disable SPI mode

1: Enable SPI mode

Bit 5 (SRO):

SPI Read Overflow bit

0: No overflow

1: A new data is received while the previous data is still being held in the

SPIR register. Under this condition, the data in the SPIS register is

destroyed. To avoid setting this bit, user should read the SPIR register

although only transmission is implemented. This can only occur in

Slave mode.
