(CKP[2:0]: Pin/Register)
Communication speed (transfer rate) selection for CircLink. There are two methods to determine the
communication speed, either through pin or register settings, depending on the specification of INIMODE
(bit 9); 0: pin, 1: register (Default is 0).
(nEHWR, nEHRD: Pin)
For the functions using Peripheral mode, refer to sections 1.5.3 and 1.5.4.
(nCMIBYP: Pin)
Selects bypassing the CMI code/encoding. nCMIBYP = L bypasses the CMI coding/decoding circuit so that
encoding is RZ form signal interface, equivalent to the ARCNET back plane mode.
(nHUBON: Pin)
Selects ON/OFF ; nHUBON=H selects the HUB function OFF, nHUBON=L selects the HUB function ON
and enables the port 2 (RXIN2 and TXEN2) available. ( in nHUBON = H, RXIN2 should be fixed to High.)
Refer to section 2.13 - HUB Function for the detailed operations.
