3.2.2 Terminal-specific register description
R32: Feature register
[0x0100]
The feature register specifies the operating modes of the terminal.
Feature bit no. Description of the mode
Bit 0 - No function
Bit 1 0/1 Output format
0: Standard output [0]
1: Alternative output
Bit 2 1 If two counters are active, the CNT_INH bit
becomes CNT_SET for the second counter [0].
Bit 3 1 The counter(s) is/are set with a positive edge of the
CNT_SET bit in the control byte [0]
Bit 4 1 The internal function for setting output OUT1 is
active [0].
Bit 5 1 The internal function for resetting output OUT1 is
active [0].
Bit 6 1 The internal function for setting output OUT2 is
active [0].
Bit 7 1 The internal function for resetting output OUT2 is
active [0].
001 32-bit up/down counter [001].
24-bit if alternative output format is active.
010 Standard output: 2 *16-bit up counter
Alternative output: counter0 is 8 bits and couner1 is
16 bits wide
The counting frequency is limited to approximately 5
kHz.
[Pulse width > 100 microseconds]
100 32-bit gated counter
24-bit if alternative output format is active
gate input low: counter is disabled
Bit 10, 9, 8
101 32-bit gated counter
24-bit if alternative output is active
gate input high: counter is disabled
Bit 11 0/1 Counting direction
0: Up [0]
1: Down
Bit 12 1 Terminal bus access is polled if the bit is set [0]
Bit 15, 14, 13 - No function [0], don't change
