I/O Function
I Timing select. 0 selects external sampling timing 16 x TXC from pin 2,
TMG. 1 selects internal sampling timing.
I Timing. Square wave timing signal 16 x TXC (TSL = 0) or 128 x
TXCmax (TSL = 1).
Max f = 10 Mhz when VDD = 5v and 5MHz when VDD = 3.3v.
O Oscillator. Output for crystal. If used, the crystal is connected between
pins 2 and 3.
I Transmitter timing (MAS9138 only).
Synchronous square wave timing for transmitter. The transmitted data
output, TDO is synchronized to the rising edge of TXC. The duty cycle
of TXC has to be 50% +/- 5%.
I Character length. The total character length including one start bit, one
stop bit and possible parity bit is selected with the CL1 and CL2
signals.
I
I Extended signalling rate. The tolerance of the synchronous bit rate can
be:
XESR = 1 (basic signalling rate) TXC -2.5%...+1.0%
XESR = 0 (extended signalling rate) TXC -2.5%...2.3%
