HOST DATA REGISTER (HDR)
The HDR register holds the data value of the corresponding bits of the HDI08 pins which are
configured as GPIO pins. The functionality of the Dxx bit depends on the corresponding
HDDR bit (DRxx). See Table 8-6.
8.5.9
DSP-SIDE REGISTERS AFTER RESET
Table 8-7 shows the results of the four reset types on the bits in each of the HDI08 registers
accessible by the DSP core. The hardware reset (HW) is caused by the RESET signal. The
software reset (SW) is caused by executing the RESET instruction. The individual reset (IR)

Read only bit. The value read is the binary value of the pin.
The corresponding pin is configured as an input.
Read only bit. Does not contain significant data.
