• Manufacturer Part Number: ht82m75r
• Description: I/o Type 8-bit Otp Mcu
• Manufacturer: Holtek Semiconductor Inc.

Note:
Rev. 1.10
WCOL: set by SPI cleared by users
CSEN: enable/disable chip selection function pin
SBEN: enable/disable serial bus (0: initialise all status flags)
TRF: 1 = data transmitted or received, 0= data is transmitting or still not received
CPOL: I/O = clock polarity rising/falling edge: For SPIR Register.
If clock polarity set to rising edge (SPI_CPOL=1), serial clock timing follow SCK, otherwise (SPI_CPOL=0)
SCK is the serial clock timing.
master mode: 1/0 = with/without SCS output function
Slave mode: 1/0 = with/without SCS input control function
when SBEN=0, all status flags should be initialised
when SBEN=1, all SPI related function pins should stay at floating state
