PIN NO.

PIN NAME I/O/Z DESCRIPTION

PZ PN

PZP PFP

GPIO18 51 41 I/O/Z General-purpose input/output 18

SPICLKA I/O SPI-A clock input/output

SCITXDB O SCI-B transmit data

XCLKOUT O/Z Output clock derived from SYSCLKOUT. XCLKOUT is either the same frequency, one-

half the frequency, or one-fourth the frequency of SYSCLKOUT. This is controlled by

bits 1:0 (XCLKOUTDIV) in the XCLK register. At reset, XCLKOUT = SYSCLKOUT/4.

The XCLKOUT signal can be turned off by setting XCLKOUTDIV to 3. The mux control

for GPIO18 must also be set to XCLKOUT for this signal to propogate to the pin.

GPIO19 64 52 I/O/Z General-purpose input/output 19

XCLKIN I External Oscillator Input. The path from this pin to the clock block is not gated by the

mux function of this pin. Care must be taken not to enable this path for clocking if it is

being used for the other peripheral functions.
