Technical data subject to change
Version 1.0
RELD1_LOW & RELD1_HIGH :
These two 32-bit registers contain user data only in the lower 16 bits. Each of the upper
16 bits is reserved for a special signature (see also 'write protection'). Thus, the 32-bit
value for the counter consists of the lower halves of both registers. Only the upper 32 bits
of the reload value can be specified for these counters – the lower 4 bits are always logi-
cal 0. The register values must be changed only when the counter is stopped
(Run/xStop_ZX = 0).
WDOG0 & WDOG1:
These two registers can be used to read the current values of the two counters. Only the
upper 32 bits of the current counter value can be read for Counter1. The content of the
two registers will be updated after each increasing edge of the counter cycle clock
(CLK_WD). Thus, without requiring the wait state, a read access to these registers al-
ways returns the contents of the two counters after the last recognized counter cycle
