(3) CSIEn transmit data buffer register (CEnTX0)
The following shows the CEnTX0 register operation in reading/writing.
(4) CSI data buffer register n (CSIBUFn)
The CEnTX0 register is a 16-bit buffer register that stores transmit data.
When transmit data is written to this register, the data is sequentially stored in the CSIBUFn register while the
CSIBUFn pointer for writing is incremented. Writing to the CEnTX register for the number of times exceeding
the set value of the CEnCTL3.CEnSFN3 to CEnCTL3.CEnSFN0 bits (CSIEn transfer data count) during the
continuous transfer mode (CEnCTL0.CEnTMS bit = 1) is prohibited.
When the data of this register is read, the value of the transmit data written last is read.
The CEnTX0 register can be read or written in 16-bit units.
When the higher 8 bits of the CEnTX0 register are used as the CEnTX0H register, and the lower 8 bits as the
CEnTX0L register, these registers can be read or written in 8-bit units. When reading in 8-bit units, be sure to
read the CEnTX0H register and CEnTX0L register in that order. In addition, write the transmission data from
the lower bits, regardless of the transfer direction. If the transmission data is 8 bits, write the CEnTX0L register
only.
Reset sets this register to 0000H.
Caution Accessing the CEnTX0 register is prohibited in the following statuses. For details, refer to
By consecutively writing transmit data to the CEnTX0 register from where it is transferred, up to sixteen 16-bit
data can be stored in the CSIBUFn register while the CSIBUFn pointer for writing is automatically incremented.
In the continuous mode, the data received in the CSIBUFn register can be sequentially read while the read
CSIBUFn pointer is automatically incremented, by continuously reading the receive data from the CEnRX0
register.
