HARDWARE MODE PINOUT (BIS1 = 1, BIS0 = 1)
Figure 4-3
5. HARDWARE MODE
In hardware mode (BIS1 = 1, BIS0 = 1), pins 1-19, 23, 25, 31, and 44 are redefined to be used for
initializing the DS21348. BPCLK (pin 31) defaults to a 16.384MHz output when in hardware mode. The
RCL/LOTC (pin 25) is designated to RCL when in hardware mode. JABDS (CCR4.2) defaults to logic 0.
The RHBE (CCR2.3) and THBE (CCR2.2) control bits are combined and controlled by HBE at pin 11
while the RSCLKE (CCR5.3) and TSCLKE (CCR5.2) bits are combined and controlled by SCLKE at
pin 4. TCES (CCR2.1) and RCES (CCR2.0) are combined and controlled by CES at pin 12. The
transmitter functions are combined and controlled by TX1 (pin 15) and TX0 (pin 14). The loopback
functions are controlled by LOOP1 (pin 17) and LOOP0 (pin 16). All other control bits default to the
logic 0 setting.
