I/O8PD
Memory Address Bus:
MA2 Addresses memory locations within the external memory.
SEL_CLKDRV. During nRESET assertion, this pins will select
the operating clock mode (crystal or externally driven clock
source), and a weak pull-down resistor is enabled. When
nRESET is negated, the value will be internally latched and this
pin will revert to MA2 functionality, the internal pull-down will be
disabled.
‘0’ = Crystal operation (24MHz only)
‘1’ = Externally driven clock source (24MHz or 48MHz)
Note:
If the latched value is ‘1’, then the MA2 pin is tri-stated
when the following conditions are true:
1. IDLE bit (PCON.0) is 1.
2. INT2 is negated
3. SLEEP bit of CLOCK_SEL is 1.
If the latched value is ‘0’, then the MA2 pin will function
identically to the MA[15:3] pins at all times (other than during
nRESET assertion).
