Reads receive data
<When set to IN buffer>

Writes transmit data
Note:The upper 8 bits (b15 to b8) become invalid in the 8-bit mode (using the Octl bits or *HWR/*BYTE pin).
(1) CPU_FIFO(CPU_FIFO Data) Bits (b15~b0)
The receive data from the CPU side buffer is read or the transmit data to the CPU side buffer is written
through this register.
When set to OUT buffer (EPi_DIR bit = “0”), the receive data from the CPU side buffer is read through this
register.
When set to IN buffer (EPi_DIR bit = “1”), the transmit data to the CPU side buffer is written through this
register.
Make sure that the Creq bit is equal to “0” before reading/writing these bits.
Note:
Refer to “3.2 FIFO Buffer” for CPU/SIE side.
Note:
When set to 16-bit mode, the M66291 is capable of recognizing the byte data written. Hence, it is possible to
transmit the odd byte data by setting “1” to the IVAL bit after writing the byte data.
