1.2 Pins Related to Transmission/Reception
(1) T
X
DA (Transmit Data A) and T
X
DB (Transmit Data B) ... Output
These pins output transmit data.
(2) RxDA (Receive Data A) and RxDB (Receive Data B) ... Input
These pins input receive data.
(3) XI1A/STR
X
CA (Crystal Input 1A/Source of Transmit Receive Clock A) ... Input
XI1B/STR
X
CB (Crystal Input 1B/Source of Transmit Receive Clock B) ... Input
The functions of these pins change depending on the setting of CR15: D7.
(a) When CR15: D7 = “0”
These pins function as the STR
X
C pins, and input the transmission and reception clocks, or input source
clocks to the internal BRG (Baud Rate Generator) and DPLL (Digital Phase Locked Loop).
(b) When CR15: D7 = “1”
These pins function as XI1 pins and connect one end of the crystal for transmission/reception clock source
oscillation.
(4) XI2A/SYNCA (Crystal Input 2A/Synchronization A) ... I/O
XI2B/SYNCB (Crystal Input 2B/Synchronization B) ... I/O
The functions of these pins change depending on the setting of CR15: D7.
(a) When CR15: D7 = 0
These pins function as SYNC pins. The functions of the SYNC pins differ as shown in Table 1-6, depending
on the setting of CR4.
(b) When CR15: D7 = “1”
These pins function as XI2 pins and connect one end of the crystal for transmission/reception clock source
oscillation.
